I just pulled my floor mat up to install speaker wires and found alot of water. I had gotten floor wet to clean mud out and soaked the padding. There is no drains for water so i drilled a few in the wire chase groove near the door sill cover forward screw, there is a small low spot 2" long and 1/2"wide area perfect for a drain hole. the truck is a 2001 quad 4x4 3500 mls so look out.
