Ok, thinking about buying a car hauler type trailer, pulls 3-4 cars or so, and it is a "fifth wheel" type trailer (Pics below) I think this means it normally uses a ball, mounted in your bed of truck over your axle, on a dually, etc. What I am wanting to do is just MOVE the trailer by itself around as needed and do NOT want to actually install the ball in my truck bed. So this would be a trailer by itself, NOT loaded with cars!!! So my question is this... could I use one of those adjustable ball mount hitches in my normal receiver to put a ball up to the same height as my pickup bed and move it around that way? My worry is 'leverage' in that the weight on the ball is likely higher than normal and of course we are now hanging this behind the truck instead of over the rear axle? What say ye?
