Yeah so I absolutely love the design and I have thought about doing something like this without having the trailer area. Basically make it a hard shell camping cover with general storage/haul ability when not being used for camping.

I was imagining using something like an old Rodeo or something cheap? But I am realizing that using an X probably really makes the roof space an extra bonus!

So disclaimer: if I copy you it will be A) different, B)Not be soon and C) probably be in terrible condition compared to what you have there!

again, Great fab!
