Since I have some rental properties, vinyl and wear problems is something I know more about than I would like.
It is likely your biggest problem will not be wear, as such, but rather damage from cuts. Even the thickest vinyls cut much more easily than I would like. Of course, you probably are not going to have a tenant with a kitchen chair missing the bottom glide on one leg.
BUT!!!! My flooring contacts tell me there is a new kevlar impregnated sheet flooring that is guaranteed not to cut. One of them put down a large section in his highest traffic area and it does seem to be doing amazingly well. I do not have the brand name(s) available, but could get it if it is important. Lots of patterns, very high price for vinyl, but then you do not need much even for a 34' coach.
