<P>I tore apart an old slide in that an owner simply wanted out of his yard, and got a lot of parts off of, including hydraulic jacks on poles that were mounted on the four corners, which i was actually just outside beginning to mount them so i can jack it up and drive out from under it. It is mounted to the bed rails with bolts, so the bed of the truck acts as the bottom half, saving weight over a true slide in, but i have built a base the same size as my truck bed to set it on so it will remain enclosed and out of the weather while off the truck, and i can use it for storage or bike shed while not using...not too much or it'll be full when i want to use it again. Basically just a shell inside, i don't need a lot of permanantly mounted sinks or stoves, etc. I'd rather be easily able to modify the inside to suit my particular need. I'm in construction so i actually bought less than 100$ in materials for it. It is wood frame with 1/2 in plywood. I cut 2x6's in half to make 2x3's and used them for the frame since i happened to have a bunch already. its very strong. The exterior is simply very thin aluminum, coil stock used in vinyl siding. It comes in 50ft. rolls x 2ft. wide that i can custom bend with my break( i do a lot of vinyl siding installations, so i had a bunch of that too.) So the exterior is completely covered and waterproof. I do love the gabled roof... it gives me so much more headroom, makes the whole interior feel a lot more spacious, and prevents leaks. The hieght is just under 11ft. It does draw a lot of attention though, my neihbor does the carvings decorating the camper, and he just came over with them the day before i left and offered them so i said go ahead and put them on. He studies a lot of different religions and social groups and a lot of his work is influenced by that, i'm sure.</P>
