I had a very similar trailer, a Rockwood 2604 WS. My main caution is the tongue weight was a lot higher than the brochure said. I think mine was almost 900pounds. Couple that with the low payload of the ED (my Laramie door sticker said 1200 pounds) and you need to be careful about loading the front storage on the trailer and piling stuff in the truck. I highly recommend Timbergrove air bags. Adjust your WD hitch per the manufacturers instructions first, then put just enough air in the bags to lift the back of the truck less than one inch. My theory is this is like adding stiffer springs in the back to help reduce porpoising and bottoming out. The truck had no trouble towing 6,300 pounds through the Adirondacks. One other recommendation; after you adjust your hitch, go to a CAT scale and get your weights checked. In my case moving only about 100 pounds more to the front axle made a big difference in the stability of the rig.
