Automotive carpeting for the walls

I think I'm going to use automotive carpeting for the walls. Not the loop pile but the cut, fuzzy stuff. I think it will as SOME insulation value but will definately help with noise, too. The condensation is somewhat of a concern but I don't think it will attract any more than a wood wall will. Wipe it with a dry towel and let it air dry. At least the water wouldn't run down and get under the bedding. Now, the stuff I'm talking about is not floor carpeting with a heavy backing but a lighter material used for door panels and other areas that don't have heavy traffic on it. I built a rear speaker panel for my El Camino and just glued it to plywood with contact cement and it turned out great!! Granted, I don't sleep two people in the Camino but I still think it is something to think about.
