That's interesting... it's not really a trailer, it's a fixed platform supported at the front by the receiver, and in the back by dolly wheels. I'd be concerned about those tires/bearings at highway speeds. I know that there are small two-wheeled utility trailers that use them, but if it were behind something like a 5th wheel where it can't be seen, felt, or heard until the golf car is bouncing down the road on it's own... I dunno...
