Hi Don/Mary, quick question on the seat rails, why did you choose to leave them together with rubber/plywood subfloor?
We bought the exact same bus from a place in Glendale AZ and I feel the rails are a part of the chassis to frame connection. Also, except for a few tiny cracks in the rubber surface the plywood is not deteriorated at all with metal subframe lacking any rust or damage of any sort. I'm thinking a layer of insulation with bamboo flooring on top should suffice.
I just need to hear your reasoning for moral support..!
