Actually, from what I've read, the main limitation of towing has mainly to do with how safe the combination is at highway speeds. Most states do not limit speed when towing so in order to be rated to tow a trailer, a vehicle HAS to be able to do it safely at the highest speed allowed, which in the USA is currently 85 mph (perhaps higher? Montana?).
I wouldn't want to tow any kind of trailer behind a bolt at 85 mph.
