After getting the floor off my 1992 Wayne G30, I was a bit surprised by the floor. I was expecting flat sheet metal across the bottom shell of the bus, but it is actually corrugated metal with flat mounts for the seats welded on top, and flat pieces welded along the front sides for whatever reason.
I am deciding how I should proceed. Originally, I planned on cleaning and painting the metal, 1/2" rigid foam board with occasional square wood supports, 1/2" plywood, finished flooring. With this new base layer, I am not sure what needs to go directly on the metal do avoid damaging the insulation.
I am figuring my two options are: removed the metal plates and put more support for the plywood to not crush the foam board; or add wood around the plates to create a mostly flat surface for the foam and continue as planned.
Either way, I will take a wire wheel to surface rust and put rustoleum over it. One of my biggest concerns (and I should probably just get over it) is height. I am 6'0 and so is my bus. With the original floor I can stand up straight with shoes on. I would love to still have this ability.
I should add that this is not going to be a full time living bus, and will be used much more in extreme heat than extreme cold. I still want to get good insulation on the walls and floor, but I am starting to wonder if I should just cut some rubber and add a 1/2" sheet of plywood and keep it super simple.
