Hi Steve, over the years we've seen all kinds of replacement materials used, from shiny diamond plate, to "picture frame" glued/nailed to the cabinet doors. The interior of the picture frame has been painted or wall papered, or actually used to place family pictures and camping shots. Byron Kinnaman is a wood carver and has carved/burned forest scenes into his trailer cupboard doors. One of the more innovative mods I've seen, involved using poly cutting board material the individual purchased at the dollar store. It's up to your imagination and ability to decide what would work best for you and would definitely make the trailer uniquely your own.
