Ken, we previously had a 2002 Winnebago Journey that had a lot of carpet and some ceramic tile in the galley and bath area. We replaced all the carpet with wood-look vinyl plank flooring and it really made an improvement and updated the look. We had it done by a professional RV shop since there was a big living room slide involved.
Our current rig has a lot more ceramic tile throughout the coach and a lot less carpet. However, the carpet looks tired so we are just replacing the carpet with new, higher quality carpet.
There are a lot of flooring options these days. The options in vinyl flooring seem endless. There is also laminate flooring.
