Changed the bedroom area steps today on my 2800rls from the silly single to a double setup with storage. Some 3/4 plywood and scrap 2x4s was all it took. I added carpet from Lowes for only 9 bucks off of the bulk rolls and 2 small hinges for storage underneath. Much easier to go up and down now. I cant even imagine the logic of putting in a single step for a 21 inch height difference. Nice 1 day project for anyone interested.
