Thanks, Ultarc! I never thought of converting a shell into a tonneau! With the size of the bed, pretty much any shell could be converted...
Most shells are fiberglass, arent they? I could even recycle the windows, and make smaller mods using the scraps... Im definitely going to start looking!
That tonneau build also looks awesome, Ill try translating some of that article, but I got the jist from the pictures. Very creative!
