When I was looking I ended up coming across these guys.

They make a hard tri-fold that's $600 new,

Cheapest I could find for new and it's made in usa.

I was looking at their products and at Tonno Pro's stuff. Tonno Pro has one for my truck that's right at $500 but it doesn't have a keyed lock, just two folding jams that keep it held down from inside the bed. Going to get a electric lock for my tailgate when I pick a cover up, wire it in with the secondary lock on my truck... drivers door unlocks first then a second press unlocks the rest of the doors, thats what I'm wiring it to.

I might look into building one, I have a friend that owns a metal shop that can get me aluminum diamond plate pretty cheap, I'll just have to figure the whole folding and keeping it sealed part out. Oh and he powdercoats, so that's covered too.
