I have a custom bumper on my hitch that was welded to hold the generator so i know its strong. (its mounted to the frame of the PUP), I want to put a hitch there to carry the bikes. The only problem i have is that the lift system is right in the middle of the bumper, and i think the hitch would have to be mounted off center, and carry the bikes off center. has anyone ever done this? is that a bad idea?
