Grey water tank cover
I have installed a new greywater tank in my '59 tradewind. It will hang below the bellypan about four inches, but it is forward of the axle so i don't think it will drag on anything. It is supported by a flange along both sides with lots of grade 8 nuts and bolts.
I haven't figured out how to insulate it or cover it. I think I will use 3/4" polyisoncyanate board (R value 5), and i might add a heat blanket.
My question is: rather than aluminum, galvanized steel or plywood, I would like to lay up a fiberglass cover for the tank? I think I could make it thick enough at the leading edge to reject any road hazards, and thin enough at the bottom, sides and back to keep the weight reasonable.
Has anyone done this? Good idea? Bad idea?
