Pretty cool plan, very well thought out. I think the reason that you got lots of views and hardly any replies is because most people dont think like you do. I happen to think along your lines. I think it is an excellent plan. The only thing I would do differently would be to conceal it some how with some kind of fold down sides and back. When folded up, it simply looks like a ordinary box on your truck. There are people out there that would see the worth of this contraption and may want to steal it, so I would have to hide it from plain site with the fold down sides, and then only reveil it to show it off to friends or just using it to go camping.
