Mega Progress!
Ok so yesterday with the help of my brothers I did a ton of cutting and welding and made the superstructure for the camper as well as the frame for the poptop. Middle brother is a burning man guy and got me access to an art co-op place where they make tons of sculptures and such. The metal shop there is outta sight! I only used saws and welders but they've got just about everything you can imagine for metalwork. Now to convince the girlfriend to move out to a giant warehouse that I can fill with tools...
Anyway, thanks to my two brothers, the Box Shop, and my excellent partner who let me do this crap on mother's day.
We started by making a perimeter frame that matches the bed and bolted it in place with 15 3/8 fasteners. The superstructure is almost all 2x2x.065" mild steel, which is pretty light. I added gussets and my bro had lots of 1.5x1.5 and 1.5x2x.065 laying around that I pilfered.

The trickiest part was making the frame for the tonneau cover to fit on and be able to seal. Apparently newer truck beds are quite curvaceous so we had to build some bent into our tubes. I really wanted to use the tube roller and make it out of round tube but it was in use and I have no idea how to operate one anyway. Maybe later as a revision, we'll see. We just sliced cuts into the tube without going all the way through and adjust with some trial and error.
By the end of the day we had the frame and top on and adjusted so I stayed a wee bit longer and attached the proper hardware. Had to see it in action after all that!
Brought her out into the light today. Here's my friend Joe appraising it and providing some scale. I'd like to get the top to open higher by adjusting the lift arms, but one thing at a time. Also in these picks I've got a ratchet strap handy to hold it down- ran out of proper hardware.

Its a giant square! the door height is the same as an e350, like the sportsmobile we originally wanted. We now have a 4x4, solid axle, diesel v8, poptop camper (almost)! In your face sportsmobile!!!!!! p.s. I'm poor.
Lots left to do but I'm pleased with the progress. Picked up my wall panels today, also known as wood, and will be receiving some sealant here quite soon. Got a suprise idea for the tent material as well.
ZANG!
