I tow my boat using my Fifth Wheel Hitch most of the time, I always make sure that my Fifth Wheel Hitch and the pin box is the same level as whatever I am towing. I think it is reccomended to give 6 inches gap between the top of the pick-up walls and the underside of the front of the trailer to prevent pitch and roll of the trailer and I don't have any backing problems at all. I tried to find photos of the hitch I am using and I found this
