    This reminded me....I have several "settings" on my airbags depending on the TW of the trailer. The idea behind that was that I didn't want to make adjustments to the WD setup each time I loaded the trailer differently. With the different settings of the airbags I can make the heights (front and rear) of the TV the same with different TW.

    If you TW changes, the squat on the TV changes which requires and adjustment to the WD system. The method I use may not be perfect, but it is close and much easier.

      moved trike to forward most tie downs. About 5’, straddling the tandem axle, with engine dead center.

      TW increase by 220# and steer axle decreased by 80#. WD totally Max’s out

      UGH!!!!!!!!!!!!!!!!!

      Propride basically suggested same as here except he said to do air bag fill up at the very end. I asked them about their 1400# limitation

        What If this is not “sway” but rather too much tongue weight pushing the rear end of the truck around, which causes this long (34’)bumper pull trailer to feel like sway.

        Instead of moving the trike forward, and thus increasing the TW, maybe I should be going in the other direction.

        My GTW is 10480 #. New measurement yesterday at CAT scales. So if our target is a max of 15%, that would be 1572#. Right now my TW is 1800#

          A Sherline scale may help you out with your situation, plenty here use one to determine tongue weight. Moving the mass back to reduce tongue weight will improve your situation but may also cause some more grief in terms of having too much weight either over the axels or behind the axels of the RV. Toyhaulers are a bit tricky to get to the sweet spot. I would also think that a set of 2000# or more if available bars may be what you need.

            kdocker Try adjusting the attitude of the truck to pitch it down toward the front with the bags and before you attach the trailer.

            Then adjust the WDH per the instructions. Weight will be transferred by pitching the truck forward, will increase rear suspension travel and will better plant the steer axle for stability and control. Then the WDH will further transfer mass to the front.

            When adjusting up the rear of the truck for increased height, you may need to adjust the hitch height to keep the trailer level once its all set up.

              Its not that its pushing the rear of the truck around. But rather removing weight from the front which creates oversteer and wander.

                I understand. I read a interesting article (I’ll got back and find it and share the link) about too much tongue weight. In summary it said with too high of TW you lose steering and front end resistance (which is what you just said) but there is also a second set of physics on the rear end of the TV that causes it sway as the resistance of the front decreases.

                bottomline, the trick is to get it all balanced which has to start with getting the front wheels back to normal with the toy hauler attached.

                  Hi Kelly,

                  This was exactly my theory way back in posts 2 and 7.
                  Jim and I do tend to agree on most things LOL! . . . (we come from very similar backgrounds)

                      I’m going to try 2 things before a pull the trigger on looking for a GMC 3500.
                      1.) Move trike back to the back of the garage AND max out the weight distribution with my Propride.
                      2.) Same as #1 but replace ProPride with a weigh-safe hitch with a 2000lbs rating.

                      Unless someone can make a recommendation for another WDH with 2000lbs OR MORE

                        Let us know how it works out. I'm very curious what you find. If we lived closer, I'd loan you my truck for a day to see if there's any difference.

                          I have read through these and I think Rob and Jim are right on. Since you are so familiar with the scales, I would suggest you not work with the payload number and instead work with the GVWR of your truck (I assume 10k) less your actual truck weight from the scale (8,520). That would give you a working payload of 1,471, but that accounts for your toolbox and anything in your truck. Not sure if you had your wife with you so you might need to account for that. If you are working off of the axle ratings (and okay with exceeding the GVWR) do the same math, your axle rating (6,200) less your actual drive axle weight from the scale (3,620) which gives you 2,580 for the trailer tongue.

                          Those numbers make me think the total weight placed on the truck is "probably" not the cause of your sway. I am not saying its okay to exceed the GVWR, but I do not see that as your issue. I think the guys are right and its removing the front axle weight coupled with the ratio of tongue weight to trailer gross weight. If you are looking at a new truck I might suggest a long bed, the increased wheelbase here could make a big difference in reducing the lift the tongue puts on the steer axle.

                          As far as another hitch, I generally am not a huge fan of correcting sway with a hitch. I like to have the rig set up to tow sway free, and then have sway control for a safety net for cross wind, trucks passing etc. That said for a trailer that heavy and that long I would be looking at a Hensley.

                            I'm taking mine from Peoria to Texas this weekend. I'll load it with the RZR as far forward as it will go, drive for a couple hours then move it back and see if I notice any difference. I'll also make a note of the effect on the TW (weigh-safe scale).

                                kdocker 1,460lbs. I carry a couple hundred pounds of water, a tire, and miscellaneous stuff that doesn't weigh much in the bed of the truck. Don't know how much of a difference it will make, but I will move the water from the rear to the front of the bed.
