Have 2 large tubes of silicone sealant and a shop vac. on hand & remove the large cover on top of the cab. After a thorough cleaning, seal up every gap where air might leak. Also check the speakers, I'm guessing the paper is tore allowing leaks. I completely sealed the speakers off from above to stop the air flow through them. Wire brush off the old sealant from both the roof & lid. [Reply]  [No Email]
