re smell in cab
make sure the cowel seal is in place and tight
mine is out right now and it stinks in the cab
trucks with no AC have vents on both sides
with AC only the pass side

thanks buddy, I didn't have a cowel seal when I first got it. I put one in after a few days and it did cut back the smell, but still pretty bad.

I found a few small holes in the cab when the interior was pulled out. I'm going to sound mat the cab here in a few days so I'm hopping that will help.

I'm thinking some aluminum tape over the small holes then the sound mat sound should stop any air from getting in through them and the tape should stop any goop from oozing out when the mat heats up...
