U-Haul car trailer experience?

Rented one to tow my car back home when I bought it, about 4hrs. I did not have a problem. A friend of mine just towed his Demon from Ohio to SC and it went ok but the we had to fix the trailers lights 1st (harness issue).
Yep, that was my Demon. No problem other than the trailer lights on the car trailer. I've rented about 3 U-Haul (in closed) trailers in the last 4-5 months with few problems. I would recommend renting the trailer from an actual U-Haul center and not Joe Blow down the street. If you get an in closed trailer, get the 6'x12' duel axle. That one trails much better and has inside tie downs.
