We had a residential refrigerator installed in our coach by Oregon Motor Coach Center in Eugene, OR two years ago As I remember, the cost was around $1800 plus the refrigerator. They did a great job and matched the wood trim perfectly. It's not the same, but we had the carpeting replaced in our coach last month. We have tile from the front to the bedroom, so the carpeting was in the two front slide areas, under the driver/passenger seats and the bedroom with two slids. That was done my a local carpet installer, and the labor was $800 for three days work. He does not do wood, only carpet. I hope this gives you some idea of the costs, at least what we paid.
