I have one. It's a bit on the light side for my setup, so I'll be going with the Equalizer or Reese Dual Cam for my next hitch. The E2 works pretty well for us even at its maximum load; sway has been well controlled, weight distribution is adequate (verified on scales), and it's fairly easy to use. As mentioned in some of the posts referenced above, it is kind of noisy because the sway control is friction based. I lubed the ball and the head part of the bars with general purpose grease, and put a little Vaseline on the friction sway components (YMMV, many people say you shouldn't do this because lubricant on the friction sway components negates their effectiveness at controlling sway; I did it because Vaseline is not an efficient lubricant under load, but it makes the hitch quieter and I've noticed no change in performance).
Bottom line, if I had it to do over again, I would've kept my money from the dealer and gotten a Reese or an Equalizer in the first place; but that's what the dealer had at the time and I didn't know any different. But the E2 is not a bad hitch IMO.
