I've been using the same Reese Dual Cam setup for almost ten years now and I love it. I towed without the Dual Cam for almost a year before upgrading. The difference was unbelievable.
I'm sure there are better systems out there, but this was the one that fit my budget. I've never been sorry. And Reese has been great to work with. One time I cut a turn too short and one of my WD bars fell off. I went back to find it the next morning, but never could find it. When I called Reese to try to buy one single WD bar, the tech I talked to asked me a few questions and then determined that it fell off because of a defect in their hitch head. So instead of selling me another bar, he sent me a free set of bars and a brand new (redesigned) hitch head. Good stuff.
