I was wondering if anyone else was having this problem or if my truck has a defect. I have a 2008 Colorado Extended cab and I live In Washington state so it rains about every day. The problem is that in both corners in the very rear of the cab the carpet is always very damp and it gives the truck a moldly smell. Drying it and a little Fabreez takes care of that, but two days later the carpet is wet again. Any sugestions?
