Stayed With Carpeting for the Warmth
We replaced all our OEM carpeting with new carpeting. Company we used does a fair number of RVs and was able to recommend a proven "family" of products to us. As I recall, the carpets they presented all had a soft, flexible back (so they can wrap around slide edges, etc), a very tight closed loop weave, a short pile, and were of higher quality (of course) to withstand the predictable wear patterns common in RVs. I don't remember the brand names, unfortunately, but ours was $1600+/- for carpet/pad/glue (including a 12 foot runner that we roll down the center when the slides are in).
With the scraps he made covers for the steps and two small rugs for the bathroom, etc., by sending the extra pieces to a binder. The carpeting on the steps turned out to be a very nice bonus.
Total project was four days. I spent one day up front removing all of the furniture pieces and closet mirrors, etc, and one day at the end to put it all back together. The three-person carpet install team took two full days to remove the old carpeting and install the new. Total installation costs ran about $1000, as I remember.
We chose a medium brown color called "Dirt," which we have learned to appreciate over time.
