Hey Dan, looks like you've got another 6 years left in that carpet. I had an aluminum Lowe several years ago that going down the highway, the whole rear deck carpet flew off. It was in bad shape, with literally 1/3 of the carpet torn or missing. It looked nice after i redid it.
For me, im a carpet guy. In my home, trucks, boats. Just something about the feel on my bare feet. I do fish shoeless alot when its not below 60 degrees. That vinyl that alot of the new boats offer now would be to hot for me i think.
