A few years ago, when I was considering a heavy hauler instead of a truck conversion, I spoke to a gentleman who specialized in singling out Semis for towing big 5th wheels. When I told him that I wanted the truck to do double duty as a RV hauler and a boat hauler, he said it was not the solution. His reasoning was just as you stated, not enough weight on the rear axle for traction, especially on slick boat ramps.
