floor supported by insulation foam in a v hull?

[PSG-1]

How much would it cost to make a floor of 0.100 or 0.62" aluminum? When I see the price of just regular angle aluminum or tubes I am worries it will be very costly...
Did you cover the aluminum floor with carpet?

It cost me about 400 dollars for new material to make my floor, with brand new aluminum. Bottom is diamondplate, but the sides are regular. I welded the whole thing together like a tub, so that the sides join the bottom. Then I installed the foam board, put the 'tub' in there, and riveted it.

Ouch that is way too expensive for my budget... I will probably stick to plywood sealed and carpet covered...
