A little help folks, if you don't mind. The rear end of my 28RS-S wants to move around a lot more that I am really comfortable with. My TV is an Excursion with a HD tow pkg, the hitch is a WD eaz-lift with a single Reese Sway control. The hitch is set up to the proper height and both the trailer and TV sit level. I have got the sway control tight but I am still getting that sway from the big trucks. I am thinking that the weight of the slide out bed in the rear is a contributing factor, but even after loading the front sstorage compartment. I am still getting, what I think is a little to much sway. Any thoughts, ideas, product recommendations would be appreciated.
