Although I am selling my gray trooper, (priced at 1500$ currently, that's around the lowest I'm going) I want to finish my design of a 1st gen trooper cargo system for the rear. I'm looking for some schematics/diagrams that I can use with this.

It originally started with me wanting a way to transport several dozen airsoft weapons at once, with a secure system that opened up on the guns sorted and arranged, but it could apply to almost any type of gear, from fishing to hunting to djing.

Any suggestions on where to look for schematics? When I have it drawn out, I'll run it past an engineer pal or two to make sure it's doable, then post plans.
