I was in Cabelas and they had a "Large" seat in the bargain basement (return and closeout room). I had to order the mounting kit from the catalog. You are supposed to bolt it in on top of the carpet but the brackets looked ugly and uncomfortable if you wanted to lay on them. I pulled the carpet and bolted directly to the floor then added some pad and notched the carpet. now all you see is the 4 cuts when the seat isn't in.
