Bad Sway Problems

I recently purchased a 2012 Dutchmen 26' TT that has a dry weight of 5000#. My TV is a 2009 Yukon Denali (standard length) with the 6.2 liter engine. I also tow a small trailer & ATV behind my TT. The additional weight of the trailer & ATV is 1200#. I have WD hitch & sway bars. I estimate that the additional weight of passengers, dogs. generators and everything else adds an additional 600# to the equation. I am under my tow rating (8,500# with WD hitch) but not by much.

I experience quite a bit of sway at speeds above 50 mph especially if I am going downhill. Almost all of my trips involve mountain driving since I live in Utah. Crosswinds are a real adventure also. I am not sure what would be the best solution to solve the sway problem. I have read that the Hensley Arrow hitch or the ProPride hitch will eliminate the sway but I am not convinced that is the right answer to my problem although it would certainly help. I also have read that going to E load tires on both the TT & TV would help as well as adding airbags. The expensive solution would be to buy a 3/4 ton diesel truck but for the 10 times a year that I would probably tow my TT, that seems like a lot of money to spend for those 10 camping trips per year but my family's safety is my ultimate concern.

The dealer I bought my trailer from convinced me that my TV was adequate for towing the TT. I need some advice from someone who has had a similar experience. How should I best solve the sway issue I am having based on the information that I have given above? Thanks!

  • With the rear trailer hooked to the TT what is the tongue weight of the TT? Most likely not enough
    There is a dutchmen TT (257RBGS) that has a dry weight of 5088 lb and the tongue weight is only 5% of that 453 lb. If you started with that and then put a trailer on the rear bumper you don't have near enough tongue weight.
  • The E rated tires will help but I would also increase the tension on the WDH, probably by tilting the head more. There's also the dynamics of double towing with a light duty rig like the Yukon and its short wheel base. The second trailer is probably taking weight of the main hitch and that's never good.
    Could you post a pic of your hitch set-up?
