I'm not the one that has the problem. Just wanted to know what your previous comment had to do with soot getting on seats. Obviously your stack is too low and you are driving with your rear slide window open.

My advice to you if you have soot stains on your cab, is to acquire a product called "De-Solv-It". Specially formulated to remove the black soot. Just be careful; if left on paint too long, it could remove that also. Good luck.
