I would reverify you have your hitch setup correctly, since you have switched tow vehicles.


I spent a good day measuring and towing and repositioning the height and I'm confident it is setup good. It looks good in the photo I think. I just don't remember my old rig, in 2004, giving me as much sway. It seemed to tow pretty straight. From what I remember anyway.

Tire pressures all around definitely affect sway. Trailer tires, truck rear tires, truck front tires, all must be inflated enough to carry the load. If any pair is under inflated, you will get "directional instability."

Probably the most important are the truck's rear tires. Second most important are trailer tires.

Pickup trucks empty are light in the back. Fully loaded, they are heavy in the back, and the tire pressures have to be adjusted to compensate. If you are attempting to tow a heavy trailer with the same rear tire pressures you run normally when empty, you all but guarantee sway.

The importance of tire pressures was brought home to me years ago when some friends and I went out to get some firewood in his 15 passenger van. We loaded up about half a van full, and set out for home. I was driving, and I needed every inch of the two lane highway, it was wandering so badly. I asked the owner what pressures he was running, and he didn't know. In the years he'd owned the van, he had NEVER checked the tire pressures.

We stopped at the first gas station I saw, and I discovered his tires were all in the low 20s. They were all way overloaded even when the van was empty, let alone loaded with firewood. Pumped 'em all up where they should have been, and the rest of the way home was perfectly stable. The difference was impressive to say the least.

The first picture looked like it had chains hanging down but connected to nothing.

So did you weigh the rig? When you talk about water full and where you store stuff...that's just a wild guess if you have the weight distributed correctly. Swing by a CAT scale and see what you really have going on is a good first step.

Tire pressure critical! I run 110lbs. with my 16in rims and "G" tires! The correct tire pressure is located on the side of the tire.

Just add a sway bar to your hitch. Chain hung bars do not provide sway control.

The ReCurve R3 hitch uses a brake shoe type system for sway control. The pictured hitch is a ReCurve R6 which uses spring loaded bearings.

Turn the hitch over and check the leaf springs under each bearing. If one or more springs are broken, contact Camco [email protected] for a replacement (it may be free under warranty).

If the springs are not broken, did you engage the sway control cams?

I had sway problems with my F250/TT with sway bars. i tried turning off the sway control function in the truck. apparently sway bars and sway control work against each other. Might work for you

At five years out your original tires need to be replaced anyway. I had a Starcraft hybrid that wasn't nearly as heavy as your trailer. It came with C rated tires and I had a blowout soon after getting it. It met load ratings, but just barely. You need tires that will cover your trailer load and then some. I now have LRE tires (on a different trailer, 6500 lbs going down the road) and am very happy with them. They will carry up to 80PSI and have a speed rating of 75 or 80 MPH I believe. I run 70PSI and keep my speed as close to 65 as I can. Your plan to look at the new Goodyear is a good one. How much does your trailer weigh? Don't be afraid to move up to a LRE. You won't be putting "rocks" under your trailer.
Get the new tires, tweak your hitch some more and you will be good to go.

joytitra, just read through your thread again. I still say you need new trailer tires but another good point was raised. What truck tire do you have? I purchased a new tundra in 2008 and pulled my hybrid with it. When I got my Airstream I had to reset the hitch and it looked good. I had many miles towing with it until one day I felt a tiny bit of sway coming down a slight hill. I had some kind of P rated tire and read that weak sidewalls will create sway. I was due for new tires and moved up to LT tires and it made a lot of difference. So, trailer AND truck tires might be issue.

I had the same problem when I had my 30ft Trailer, a trucker I met told me to crack open a window on either side of the trailer to equalize pressure. It worked and the problem was solved.
