**UPDATE!**
I believe I found the problem. The last couple days it's been raining pretty good. After work today I stuck my hand under the carpet on the drivers side. The insulation was soaked again.
I did some more looking into this while I was waiting for a ride and really can't believe what i found......
Like stated before I park on a inclined driveway (not much of an incline) w/ the nose down. As I was looking I noticed water sitting in the weather stripping right around the kick panel to sill plate. I also noticed that the weather stripping is the SAME EXACT height as where the weather strip clips onto the body....hmmmmmmm.....well when you close the door the weather stripping gets bunched up like it's supposed to however, now it's HIGHER then where it clips to the body allowing water to take the easiest route to drain.....into the cab. So then I took off the sill plate and the water was just sitting in there and you could see on the weather stripping where water was sitting/overflowing over it. (it was a little more discolored then the rest of the weather stip.
I soaked up all the water and left the sill plate off to look next time it rains. I believe this IS the problem. If it is I will be cutting a slice out of the weather stripping in that spot so the water has a place to go other then going over into the cab.
I will keep you updated, but this should work for alot of you that have leaks on EITHER side.
