Anyone try to make a decent exp. vehicle out of this platform??? I have the 460, and its a pretty heavy truck. Would I be better starting with a half ton????

Before anyone can help you out, you need to explain what it is you'll be doing with the rig. Driving to South America or weekend camping rig?

Yes.
