I wouldn't say you couldn't, I'd say you shouldn't.........
The guy who delivered my Deuce brought it on a 14,000lb trailer and with a Dodge 2500 pickup. When it arrived, I could smell brakes pretty strongly on both the truck and trailer (we live in a relatively flat area, for the record) and the truck definitely was overloaded, no question about it. He also had the look of a fellow who had been just a bit on edge for the last couple of hours, and was happy to unload. Also, a Deuce is a rather tall vehicle, and on top of that high-deck trailer, it was up in the sky. It looked like a good banked turn on the highway might have set it off-center fairly easily.
In short, he got it to me in one piece and without any problems that I know of, but I certainly wouldn't have done it after seeing it on that truck/trailer combo.
