Supercab door squeak fixed!
 

I finally figured out the squeaking noise. On drivers side sounded like it was either the top latch in the back door or the drivers door latch. Nope! The back window channel is held in at the bottom with one bolt. The top just slides up into a pocket and is held in place with a little folded over metal tab attached to back channel. That tab had loosened up just enough and would squeak whenever I went over bumps. Pulled that one bolt and took it out. Cleaned, greased, and tapped that tab down. Roll your window down and wiggle that back channel ... hope this helps somebody
