I am thinking about building one, but most trucks that I see with steel flatbeds are rusty (and look bad) pretty quickly up here in the rust belt. I don't want a shiny aluminum one, as I am hoping for more of a satin black theme. Build one out of wood and paint it? Has anybody here tried? I would be making it 7' x 7', and it's main purpose would be to haul a standard 50" Rzr.
