I tow a 500 formula car in a 6x12 enclosed trailer(1100lbs) with some tools and the VX does pretty good. can cruz at 80mph. but trailer is a pretty effect wind brake. The trailer does not seem to drive the vx at all.

you should be fine. I have a dinan hitch that required me to drill in the frame rails. I should have sandblasted and painted before i put on though. trail hitch paint must be the cheapest paint out there because michigan salt is killing it.
