Not sure this is for me. I don't want to say I'm building on the cheap, because in some areas I'm spending a lot, but in some areas I don't want to spend too much either. After all, this is all going on a Deuce, not a Ford F750.interlocking aluminum slats
I have ~250 sq/ft of exterior wall to cover. Looking at an outfit on that sells aluminum slats 5.25" x 60" around $13.11 sq/ft would cost me $3300, higher than I would like. It seems it's more than I need.
I have looked at exterior ACM (aluminum composite material) panels, used on the exterior of office buildings/skyscrapers, etc. Found a panel, 1mm aluminum on both sides and 4mm plywood core, that was about $6.50 sq/ft and I thought it was too high. I'm hoping to go with something about half that cost, under $3 sq/ft
