I got this crazy idea to build a bed cap/camper shell. It would basically be a 1x1 tube frame skinned with aluminum using rivets, similar to a tractor trailer skin. The frame would bolt-in to the bed using plates on the underside of the bed to reinforce, similar to how seat belts are installed in older cars. Anyone try this?

 

It would be kinda ugly, but it would work if done correctly.

 

Theres a place in Denver that custom makes diamond plate toppers like you just described. Sounds like a PITA. How tall are you planning on making it? A used fiberglass one would be pennies compared to making your own.

I 2nd the ugliness. May I sugges some clearance lights and reflective tape down the side?

 

i got a used one a while ago and painted it to match the truck for around $150. looks as good as a cap can look and it was way cheaper and easier than buying new or building one.
