This weekend we worked on getting our totally home built RV (truck camper actually) out of our garage and on to the truck for the first time. It went smooth and feels stable on the truck. Do not undertake this type of project to save money LOL. The life experience is probably worth something.
The original idea (back when I did a quick cut and paste hack of web images to get a concept):
