aquaman - Just another thought, use luan. It's 1/4" mahogany and can look mighty fine IF you can pick thru the stack to get "the right piece". Some sheets have 'blems' and some looks good 'nuf for cabinet work. < strong + light weight. With a couple coats of urethane it sorta sparkles. OR with a bit of filler + sanding it can be painted to look like a fiberglas cover. I made one a while back for a friend, matched his truck with rally stripe. < custom + cheap. I have plans = for a short/narrow bed - can be modified to fit any. Pneumatic cylinders + 2 latches @ back + can have a spoiler if wanted.
