Working on my heat/ dust issues. After playing with different ideas , so far I temporarily placed a deflector below the roof and has promising results. Will post more after I finish and confirm the difference it makes. Appears to put lots of positive cab pressure with factory split windshield. Definantely stopped the back draft where my wife's hair is blowing forward, she really hates that. I have to shorten it up and all but may be a seller.
