I had leaks like you mentioned and what I found was that on the inside of the fender well where the side kick panel meets the floor board that it is spot welded and also has seam sealer on the joint. Over the years the seam sealer had dried out and some of it had fallen out. When I washed the truck the water would go behind the cowl extension and leak down to the seam and leak on the inside.
I managed to get it chaulked up with out removing the wheel but would have been easier with the wheel off.
