Thanks for the info, guys. I haven't made up my mind yet. The hauler has a good price, but I don't want to try to save a few hundred bucks now and then have to spend a grand to fix a bike that's fallen off the back.
I've got a class III hitch, and I've towed quite a bit of stuff with it. So while I'm not too concerned with the hitch, the suspension on my truck is going out. We'll see...
That roll-on trailer is slick, but the price is steep!
