I'd like to have a trailerable houseboat, but understand loading back on the traier is a major hassle. Why do I need a trailer? Could the wheels be mounted to the frame and lowered into position for transport? Also, could a pontoon boat with a 5th wheel tounge be hooked up to a pick-up from the boat ramp? All of this would have to be custom built, with modular pontoons with space left for the tires but I think it might work. Advice for experienced boaters appreciated.
