Steve, are the walls done or is it studs and outter skin.
Home depot or maybe craigslist for cabinets. My old
trailer, I found some used cabinets local to me, a
guy was remodeling some apartments and he had a pile
to pick from then I bought a counter top at Home
Depot. If you need wall material I would call the
trailer places in Indiana. I just re-did my currant
trailer and bought the white alum for the walls and
ceiling(about $800 in alum)
