When we bought our TrailManor, I asked about a weight-distributing hitch, and our dealer recommended this hitch. See
http://www.equalizerhitch.com/ for more information.
As soon as we pulled out of the dealers, we were very impressed with the difference between towing with this WDH and without one. We had previously pulled a popup trailer of similar weight and size, but lighter tongue weight. We had experienced some bouncing (even with gas rear shocks) and occasional sway. This WDH distributes the tongue weight between the TM and the TV, preventing sag/bouncing and sway.
When combined with the electric jack, hookup is pretty smooth and easy, too.
Happy Camping!
