I bought the e2 1000/10000 for my setup - but any longer/heavier trailer I'd go with the full Equalizer hitch with 4-point sway. Our trailer is GVWR 6050 lbs.
As with all weight distribution hitches, proper setup is key. I had to pop another $100 for a longer shank. I bought the hitch from http://www.pplmotorhomes.com/parts/r...ol-hitches.htm
- they had the best price I could find. I also bought their ball, grease, and the quieting sway-bar jackets. Before the jackets, the hitch was very noisy.
I find the e2 perfect for our towing needs. I feel little to no sway when being passed by trucks and other large vehicles. I drove last fall in 40-50 mph winds hitting me broadside --- and again, little to no sway. I did slow down to like 45 mph though.
