I found a flooring installer that installed sheet vinyl in our previous coach. Came out great. Reasonably priced because he was not a RV guy... I unbolted chairs, removed trim, etc. He removed old carpeting and the zillion staples that held it down. Then applied a leveling compound (the existing vinyl around the kitchen sink area was left in place). Then installed via glue down and trimmed the new sheet vinyl.
