I've always had carpet in my vehicles and hated trying to keep it clean. The first morning I had my Dodge truck (without carpet). I was responding to a fire call and spilt coffee in the floor. My first thought was how will I get it off the carpet. When I realized I had no carpet to worry about, I was so happy I poured the rest of the cup in the floor. Hosed it out that evening with a big smile. Looked good as new. I've noticed when I wash the cab out that a lot of water gets up under the cab mat and takes a few days to completely run out. Could this cause rust? Does it get completely dry under the mat? Any thoughts on this problem? Thanks, JB
