They make a stainless steel sink for RV's, I replaced one in my park model trailer, which uses an RV sink. Lowes stocks them, at least the one in Sebring Florida did. I checked at Home Depot and the clerk told me they couldn't even order them. Be sure to measure the opening. The problem is that RV's (and park model trailers) don't have full depth counters, as is standard in houses. There may be exceptions.
