A lot of my interior is a kinda durable thin carpet glued to the wood. There are plenty of textiles commonly used for this.
My next van will be raw wood, laminate, or something. Its nice to have the softer feel and it kinda cuts down on noise but I'm coming around to it also being kinda harder to clean, it can pick up smells from cooking, and generally I'd just like to be able to wipe it down with a damp cloth if needed.
similarly i don't really understand all the carpet people put down. we have a coin floor with one rubber backed mat in the kitchen area. it gets SO DIRTY all the time... I'm constantly sweeping it out. I can take the mat outside and beat it -- but i'd hate to have to find a vacuum or something everytime i wanted a cleaner floor.
