Sorry, I missed this post when it first came out, We did replace the carpet in front of the counter with vinyl. I had my former employer do the vinyl as my specialty was ceramic tile and I hated doing vinyl because I made way more money doing ceramic. The OEM vinyl is a perimeter glue vinyl, only glued around the edges. I would avoid ceramic at all costs, you would need to double the wood sub floor and that adds more weight. Putting tile down on the existing floor would be problematic because the floor as it is is pretty flexible and would start popping tile very shortly. Vinyl or the composite wood floors would be much better. We have a Big Sky and there wasn't any carpet by stove or fridge, but there was vinyl and wood trim. If you tear out the carpet there you will have to buy or make some wood trim for that area. As far as replacing the carpet on the slide I think that would be a bad idea also. Just reach down and lift the slide carpet up, the carpet covers all that stuff. Here is a link to my first post and slide show of the install
