I think they also have problems with the torsion bars not being up to the job and eating up shocks. I think it would be a blast!!! I would feel better doing it with a trooper or a rodeo. Something that if you encountered body damage, it is easily fixed or just not worried about.
I went to a few of the races, there is some rubbing with other vehicles, and it definitely will test the durability of the truck If it is your no kidding, I need the VX to get to work, type of vehicle, then I wouldn't risk it, but if the VX is your extra 'fun' vehicle that you sometimes drive to work just cause, then you might have something here!
