On smaller TV's, air {bags|luggage|baggage} can have a {negative|adverse|unfavorable} {effect|impact} to the {function|perform|operate} of a {properly|correctly} setup WD hitch. The truck rear sag is accounted for and {normal|regular}. I {think|assume|suppose} I {got|received|obtained} {it all|all of it} {figured out|found out|discovered} - {and you|and also you} guys {were|have been|had been} {a big|an enormous|a giant} help! I {decided|determined} {to start|to {start|begin} out|to begin} from scratch, and I {think|assume|suppose} {everything|every thing|every little thing} {worked|labored} out. The {major|main} {problem|drawback|downside} {seems|appears} to have been the ball mount I had was not designed to angle the trunnion bars down {enough|sufficient}.
I use 10psi in my air {bags|luggage|baggage} {just|simply} {to keep|to maintain} them inflated {enough|sufficient} to not be {damaged|broken}. If you do as {you are|you're|you {might|may|would possibly} be} {talking|speaking} about, make the air bag stiff first then {find|discover} that psi then {attempt to|try and|try to} {set up|arrange} the WD on the {front|entrance} of the truck. Here are my {thoughts|ideas} as {in this|on this} case {they are|they're} {only|solely} {thoughts|ideas} as {I have|I even have|I {actually|truly|really} have} {never|by no means} {done|carried out|accomplished} this. While {you will|you'll} {gain|achieve|acquire} downward stiffness you {also|additionally} {gain|achieve|acquire} upward {lift|raise|carry} with air {bags|luggage|baggage}. When you drop the {dead|lifeless|useless} weight of the TT on the ball {the main|the primary|the principle} suspension will go down, {but the|however the} air {bags|luggage|baggage} are {still|nonetheless} pushing up. As you {start|begin} {applying|making use of} spring bar {force|pressure|drive} {there is|there's|there {may|might|could} be} going to be a torque imposed {in the|within the} truck receiver and {start to|begin to} {attempt to|try and|try to} {transfer|switch} {some of the|a few of the|a {number of|variety of} the} rear axle weight {forward|ahead}.
However {you still|you {continue|proceed} to} have these air {bags|luggage|baggage} {in the|within the} equation pushing up. The 1,100# WD bars are {plenty|lots|a lot} {strong|robust|sturdy} {enough|sufficient}, {just|simply} {have to|need to|should} get the hitch head in {the right|the best|the proper} adjustment relationship with the A {frame|body} setup {to {be able|have the ability|find a way} to|to have {the ability|the power|the flexibility} to} use them..... WD bars that {strong|robust|sturdy} {against|towards|in opposition to} a tongue weight that {light|mild|gentle} {should have no|should not have any|shouldn't have any} {problem|drawback|downside} dropping the {front|entrance} of the truck {back|again} to unhitched weight and {height|peak|top}. But the hitch head and friction pad holders have {to {be able|have the ability|find a way} to|to have {the ability|the power|the flexibility} to} {allow|permit|enable} it to get there.
2.If {you have|you've|you {could|might|may} have} 700# or 800# of tongue and {using|utilizing} 800# wd bars, then the hi rise ball will {lower|decrease} the hitch head {and should|and will|and may} preload up the wd bars {more|extra} and {transfer|switch} {more|extra} weight. OK I "think" I know what {you are|you're|you {might|may|would possibly} be} {up to|as {much|a lot} as}, {maybe|perhaps|possibly}. 40psi {in the|within the} air {bags|luggage|baggage} is {a fair|a good} {amount|quantity}. We have had {folks|people|of us} use air {bags|luggage|baggage} with a WD hitch {but|however} {for different|for various} {reason|cause|purpose} then yours. Theirs was from {high|excessive} {bed|mattress} weight {changes|modifications|adjustments}. They had a 1 ton truck that had 2 {big|huge|massive} quads over the {bed|mattress} of the truck {and then|after which} pulling a TT.
In this case some {times|occasions|instances} the quads {came|got here}, {sometime|someday} {they did not|they didn't} and the {bed|mattress} {loads|masses|hundreds} {where|the place} very {different|totally different|completely different}. Then when quads {came|got here} after hitching up the WD, he would he would add air to {bring|convey|deliver} the {back|again} of the truck {up to|as {much|a lot} as} {where|the place} he had it set with the WD and no quads. The rear of the truck took the added weight and the WD was {acting|appearing|performing} {like it|prefer it} did {before|earlier than}.
{I have|I even have|I {actually|truly|really} have} been watching this thread with {interest|curiosity}, as {I have|I even have|I {actually|truly|really} have} a Pro Series SC which I {purchased|bought} in April, 2008. {I have|I even have|I {actually|truly|really} have} {never|by no means} been {totally|completely} {satisfied|glad|happy} with the {set up|arrange} in that I {could|might|may} {never|by no means} get my van {level|degree|stage}. Originally, I was towing with a 1995 Chevy G20 Conversion Van, and {while|whereas} {handling|dealing with} and sway {were|have been|had been} {fine|nice|fantastic}, I {could not|couldn't} get the rear {end|finish} sag out {without|with out} {adding|including} air to my air {bags|luggage|baggage}. I chalked it {up to|as {much|a lot} as} the rear springs {in the|within the} van being on the {soft|gentle|delicate} {side|aspect|facet}, and the van being loaded {to near|to close} full {capacity|capability}.
{3|three}.If 1 {and 2|and {a couple|a pair} of|and a pair of} {do not|don't} {correct|right|appropriate} it, then {call|name} Jayco and ask them {if it is|whether it is} OK to drill a {hole|gap} {in the|within the} A {frame|body} and {move|transfer} the friction pad up {higher|greater|larger}. They {most likely|most probably|more than likely} {will not|won't|is not going to} object {but|however} {better|higher} to {call|name} on these lighter TT's A frames. They have good {factory|manufacturing unit|manufacturing facility} tech service. Moving the pad up an inch or {more|extra} will change the WD bar loading {a lot|lots|so much} {and you can|and you may|and you'll} take out {some of the|a few of the|a {number of|variety of} the} head tilt.
Actually doing this {will not|won't|is not going to} {cost|value|price} you {much|a lot} {if your|in case your} WD bars are {right|proper} {and you can|and you may|and you'll} {maybe|perhaps|possibly} use the tow ball {you have|you've|you {could|might|may} have} now. Part of {the problem|the issue} is the relative frequency of the {car|automotive|automobile} and the trailer. Stiffer shocks will change the damping {characteristics|traits} of the rear {and probably|and doubtless|and possibly} damp out the undulations with no {other|different} change. This is {a problem|an issue} with softer {riding|driving|using} {cars|automobiles|vehicles} when {greater|higher|larger} weights are added. Increasing the spring {rate|price|fee} with the air {bags|luggage|baggage} {will also|may also|may even} shift the frequency in {the right|the best|the proper} {direction|course|path}.
With the airbags {you can|you'll {be able|have the ability|find a way} to|you {possibly|probably|presumably} can} {adjust|regulate|modify} to {level|degree|stage} the headlights and put the hitch and trailer in {the right|the best|the proper} relative positions. The {weather|climate} has been so {lousy|awful}, that I {did not|didn't} get {a chance|an opportunity} to take any {pictures|footage|photos} {before|earlier than} {putting|placing} the trailer {back|again} in storage. I am {using|utilizing} {the same|the identical} brackets on the tongue, trunnions, and 1100# bars.
This is my first {post|submit|publish} {in this|on this} {forum|discussion board}. English {is not|isn't|just isn't} my {mother|mom} tongue; please excuse any errors on my {part|half}... {I have|I even have|I {actually|truly|really} have} {just|simply} taken {delivery|supply} of my new Trillium 1300 from Great West Vans . Yesterday, I drove approximatly 200 kilometers and I {found|discovered} that the rear suspension was bouncing a lot!
The tongue weight with the propane tank and the battery is approximatly 200 {pounds|kilos}, {which is not|which isn't} that {much|a lot}. The hitch {height|peak|top} has been adjusted by the {dealer|supplier|vendor}. My towing {vehicle|car|automobile} is a Hyundai Santa Fe V and has a towing {capacity|capability} of 3500 lbs .
Has {anybody|anyone} {experienced|skilled} this problem? Do {you have|you've|you {could|might|may} have} any {suggestions|ideas|recommendations} (Firestone Coil-Rite Air Helper Springs, Coil SumoSprings Custom Helper Springs for Coil Spring Suspension, {using|utilizing} a weight distribution system). I used to tow a popup trailer with {the same|the identical} specs {without any|with none} {problem|drawback|downside}. Again {same|similar|identical} Reese PN HP trunnion hitch head and {using|utilizing} {the same|the identical} trunnion lugs Reese {but|however} with straight WD bars. The WD bars lock up at {a different|a special|a unique} angle. The {top|prime|high} trunnion lug is {advanced|superior} {forward|ahead} by {a lot|lots|so much}.
When I {said|stated|mentioned} {same|similar|identical} head, I meant {the same|the identical} Reese {part|half} {number|quantity}. Mine it the prior {generation|era|technology} {3|three} piece weleded head, yours the all 1 piece {cast|forged|solid}, {but|however} {same|similar|identical} PN. If I knew your loaded tongue weight I {could|might|may} "guess" {closer|nearer}. But I would {back|again} off 1 or 2 {teeth|tooth|enamel} of head tilt {to start|to {start|begin} out|to begin} with after the hi rise ball head drop. If you {start|begin} with {the same|the identical} {teeth|tooth|enamel} {you have|you've|you {could|might|may} have} now, it {might be|could be|may be} {dead|lifeless|useless} on or {too much|an {excessive|extreme} {amount|quantity} of} and {you have to|you {need|want} to|you must} {back|again} off {like you|such as you} {said|stated|mentioned}.
If you {start|begin} with 1 to 2 {less|much less} {teeth|tooth|enamel} {then you|then you definitely|you then} {might have|may need|might need} to add. Drop the ball 1", {back|again} off 1 tooth of rear head tilt {and you|and also you} {might be|could be|may be} {right|proper} on with the WD. What {seems|appears} so odd is why Reese {on your|in your} head set the trunnion sockets {so far|thus far|up to now} {advanced|superior}. They {had to|needed to} {almost|virtually|nearly} do it on {purpose|objective|function}. They make {those|these} hitches {trying|making an attempt|attempting} {to fit|to suit} all {combinations|mixtures|combos} of TT frames and yours {is unique|is exclusive}.
Your out of L bracket adjustment by {the original|the unique} holes and {the head|the top|the pinnacle} tilt is all {that you have|that you've|that {you've|you've got|you have} got} left to tweak. Does you're A {frame|body} {look like|seem like|appear to be} that {vintage|classic} Jay Feather? Reason I {bring|convey|deliver} this up is {just a|only a} {friendly|pleasant} heads up as {I have|I even have|I {actually|truly|really} have} seen on {some of|a few of} {those|these} {light|mild|gentle} weight Jay Feathers have a sticker that {said|stated|mentioned} 1,000# WD bars max.
Jayco had some {issues|points} early on with {higher|greater|larger} tongue weigths/WD bars on {those|these} lighter frames. Now {that you have|that you've|that {you've|you've got|you have} got} a heavier suspension Van, is the any weight aft of the TV axle {in the|within the} van? The WD hitch {is going|goes} to work on that weight as {well|properly|nicely}. And that then works on the WD bars {and then|after which} into the A {frame|body}. Need {to find|to {seek|search} out|to search out} out your loaded tongue weight, {find|discover} out the WD bar {rating|score|ranking} {and then|after which} regroup. And {maybe|perhaps|possibly} a {call|name} to Jayco {with your|together with your|along with your} vin {number|quantity} to see if that 1,000# WD bar loading applies or not {on your|in your} {frame|body}.
Ask , {what is the|what's the} highest tongue weight and WD bar {you can use|you {should|ought to} use|you {need to|have to|must} use} {without|with out} A {frame|body} {concerns|considerations|issues}. Looking {at the|on the} pic of the hitch head and WD bar, your {next|subsequent} tweak {may be|could {also|additionally} be} {to move|to maneuver} the friction pad up 1 {hole|gap} on {each side|all sides|both sides} {if you|should you|when you} can. The SC {series|collection|sequence} has {a few|a couple of|a {number|quantity} of} {styles|types|kinds} of pad mount and pending your {frame|body} width there {may|might|could} or {may not be|is {probably|in all probability|most likely} not|will not be} room to go up 1 {hole|gap}. If {there is|there's|there {may|might|could} be}, that 1 {hole|gap} will load up the WD bar {more|extra}.
If {it is|it's}, then {back|again} off 1 tooth on the hitch head angle. Once you {adjust|regulate|modify} {the head|the top|the pinnacle} or friction bar hanger, {you will need|you'll need|you will want} {to start|to {start|begin} out|to begin} over on the WD settings on the truck. Load up the TT first and get {the weight|the load|the burden} balanced out, full LP too. Then {adjust|regulate|modify} {the head|the top|the pinnacle} tilt and if {needed|wanted} {raise|increase|elevate} {lower|decrease} the hitch head on the shank to {level|degree|stage} the TT {back|again} out and {check|examine|verify} the WD one {last|final} time. When {you put|you set|you place} any {amount|quantity} of air bag {in this|on this} equation, {you are|you're|you {might|may|would possibly} be} affecting the WD hitch. Air {bags|luggage|baggage} {help|assist} {lift|raise|carry} the rear axle {but|however} {do not|don't} {transfer|switch} {much|a lot}, weight to the {front|entrance} axle and none to the TT axles.
They {also|additionally} unload the WD hitch antisway controls {and do not|and don't} {help|assist} a straining rear axle for {capacity|capability} as {they do not|they don't} {move|transfer} {the weight|the load|the burden} like a WD hitch does. Now to your air bag questions, what I am going to say is {somewhat|considerably} generic about air {bags|luggage|baggage} and a WD hitch. Like a 1 ton truck with 2 quads {in the {back|again} of|behind|at the {back|again} of} the {bed|mattress} that some {times|occasions|instances} come {camping|tenting} {and some|and a few} {times|occasions|instances} {do not|don't}. Truck {back|again} {end|finish} {way|method|means} up off {the ground|the bottom}. I was {helping|serving to} a buddy {right|proper} {here|right here} in my driveway.
The {dealer|supplier|vendor} set him up and he was having {issues|points} so I {looked at|checked out} it. What I {found|discovered} was the {dealer|supplier|vendor} gave him 1 WD bar with 1 1/8" lugs and 1 WD bar with 7/8" lugs {trying|making an attempt|attempting} {to use|to make use of} it in {the same|the identical} hitch head. They had them in old {stock|inventory} and was {just|simply} {using|utilizing} them up. I'm {sure|positive|certain} {they had|that they had|they'd} no clue what they did. They {just|simply} grabbed 2 WD and went and put them on. Since {you have|you've|you {could|might|may} have} {extra|additional|further} holes on the WD bar pad brackets, {can you|are you {able|capable} to} go up 1 {hole|gap} on {each|every} side?
But {again|once more} {check|examine|verify} your weights out first. Don't {want to|need to|wish to} {fix|repair} the WD to then {find|discover} out {you have|you've|you {could|might|may} have} an A {frame|body} {issue|problem|concern}. Some up hill will work, {a real|an actual} lot {might|may|would possibly} create some turning {issues|points}. Here is {the quick|the fast|the short} {answer|reply} with {more|extra} to {follow|comply with|observe} as I'm {short|brief|quick} on time {right|proper} now.
Rather then {buying|shopping for} {the same|the identical} head {you have|you've|you {could|might|may} have} now, {buy|purchase} {the new|the {brand|model} new} head {that is|that's} {sold|bought|offered} for the Reese SC hitch. This {will require|would require} {the new|the {brand|model} new} head and new trunnion ends. Your WD {issue|problem|concern} on the truck is steming from the angle the trunnion sockets are {cast|forged|solid} into the hitch head and your 6" {frame|body}. The new HP hitch head {does not|doesn't} have this {same|similar|identical} {issue|problem|concern} {and can|and may|and might} {allow|permit|enable} for {more|extra} WD {transfer|switch} {with your|together with your|along with your} 6" {frame|body} setup. Again, the air {bags|luggage|baggage} are used {just like|identical to|similar to} they {were|have been|had been} {permanent|everlasting} springs.
But, they do give me {a lot of|lots of|plenty of} latitude if I {were|have been|had been} {to change|to vary|to alter} {loads|masses|hundreds} {in the|within the} truck {bed|mattress}. Yes, {but|however} {they are|they're} {capable of|able to} {much more|far more|rather more}, 100psi to be {exact|actual|precise}. When I towed the trailer {home|house|residence} initially {before|earlier than} pickup up the Reese SC I {had to|needed to} add {around|round} 50psi to {level|degree|stage} the truck out.
As many have {stated|said|acknowledged} {here|right here} on RV.NET {the new|the {brand|model} new} Tundra is softly sprung on the rear {end|finish}. I've had the airbags for {some time|a while} to {deal with|cope with|take care of} {using|utilizing} the truck as a truck and hauling {bed|mattress} weight. {I have|I even have|I {actually|truly|really} have} coil air bag on my Durango and it {did not|didn't} {help|assist} {much|a lot}.I {usually|often|normally} set at 32 PSI. The WD helps and lifts up the rear of TV 1.{75|seventy five}"-2".
My enclosed trailer loaded 6600 lbs and the tongue weight 800 lbs. At any {rate|price|fee}, I {got|received|obtained} {a new|a {brand|model} new} ball mount, and did {a complete|an entire|a whole} re-installation by the newer set of {instructions|directions}. There {may be|could {also|additionally} be} a "{another|one other}" new {learning|studying} to {this {type|sort|kind} of|this {kind|type|sort} of|this {sort|type|kind} of} WD hitch. Next time you go {camping|tenting} take a pic of the hitch "up" {and how|and the way} {high|excessive} {you have to|you {need|want} to|you must} go. Your {situation|state of affairs|scenario} is {a little|slightly|somewhat} {different|totally different|completely different}.
It {sounds like|seems like|feels like} your wanting the air bag for suspension stiffness, "I think". Well left me ask, what do {you have|you've|you {could|might|may} have} {in the|within the} truck {bed|mattress} and is it {located|situated|positioned} behind the rear axle? And how {much|a lot} weight {might|may|would possibly} that be?
I know you Toy hauler guys carry {a lot of|lots of|plenty of} toys…. If {this is|that is} {truly|really|actually} that {much|a lot}, that {is {enough|sufficient} to|is {sufficient|enough|adequate} to} make a WD head {move|transfer} on the shank adjustment to {bring|convey|deliver} it up {more|extra} {level|degree|stage}. Now {before|earlier than} {you move|you progress} the shank {grab|seize} {a standard|a normal|a regular} carpenter {level|degree|stage}, 12" 24" 36" 48" which ever {you have|you've|you {could|might|may} have}. Find a {level|degree|stage} piece of concrete/black {top|prime|high}. Put {the level|the extent} on {the ground|the bottom}, {confirm|affirm|verify} yup it's {level|degree|stage}.
Then use {the level|the extent} on {the bottom|the underside} of the {frame|body}, on the siding {and then|after which} inside on {the floor|the ground}. Over the axles is supported, to the {back|again} and the {front|entrance} of the axle {may|might|could} sag. So {basically|principally|mainly} {find|discover} the {happy|joyful|pleased} {average|common} of what {level|degree|stage} is. Pick {an easy|a simple|a straightforward} {to remember|to recollect} and {where|the place} to measure spot on the {frame|body}. I {never|by no means} {want to|need to|wish to} use the weight-transfer bars to {handle|deal with} any {additional|further|extra} load {in the|within the} {bed|mattress} of my truck.
The weight-transfer {principle|precept} is designed {only|solely} to accommodate tongue weight, not for load {in the|within the} {bed|mattress} of the tow {vehicle|car|automobile}. I {do not|don't} plan on {adding|including} any weight to the {back|again} of the truck {aside from|apart from|except for} {a night|an evening} or two's firewood. Next outing, take {a close|an in depth|a detailed} pic of the {side|aspect|facet} of the hitch. It {looks|appears|seems} like from afar {things|issues} {where|the place} setup OK, {just|simply} you {needed|wanted} {more|extra} head tilt. Just driving {around the|across the} block will change fender hieghts +- 1/8" some {times|occasions|instances}. They are on springs and have a settling {range|vary}. May {need|want} 1 {last|final} tweak or your good. But, the {question|query} was {about the|concerning the|in regards to the} {claim|declare} that {adding|including} air {bags|luggage|baggage} being 50% as {effective|efficient} as a WDH.
And that {data|knowledge|information} {would have to|must} be {much more|far more|rather more} {recent|current|latest} as {vehicles|automobiles|autos} have {changed|modified} {substantially|considerably} {in the past|prior to now|up to now} 35 years. I would {investigate|examine} heavy {duty|obligation|responsibility} shock absorbers {and perhaps|and maybe} some air {bags|luggage|baggage} {to keep|to maintain} the {car|automotive|automobile} {level|degree|stage}. Mike, {when you|whenever you|if you} {check|examine|verify} your WD bars, {look for|search for} that {82|eighty two} {degree|diploma} angle I {show|present} on my pic from the centerline of the trunnion lugs to {the center|the middle} of the WD bar. Up {should|ought to} {allow|permit|enable} the angle to go down hill when the WD bar is {installed|put in}. If not, {that is a|that {may be|could {also|additionally} be} a|that {could be|might be|could {possibly|probably|presumably} be} a} {big|huge|massive} {part of|a {part|half} of} {the problem|the issue}. Yes {in this|on this} configuration you {only|solely} have 1 {hole|gap} to {lower|decrease} {the head|the top|the pinnacle}.
