Figured I share this incase anyone else is having this problem. I was hunting down a water leak in my LBZ for awhile. It would only get water in it when it was parked down hill and the water was always on the front floors. I checked drains, door seals, everything I could think of. The other day I was so aggravated I stripped the interior out and sat in the truck in a storm. The water was actually coming in the rear cab vents and running to the front. I could never find any water trails just the soaked carpet on both front floors. They both looked like this. The water was coming in from around the sides where the outside seal went bad.
