Where do the tailpipes exit? Yes it is possible to get fumes inside the cab from the rear of the truck. I have seen somewhere a rubber seal the sits inside of the cab, and seals the base of the tailgate. Do you have the side seals for the tailgate inplace? Maybe move the location of the tailpipes. Crawl under the truck and run your hands around each pipe with the engine running and double check for a leak.

On cold days when it's all buttoned up, I get groggy. On long drives this is bad.  |
