Took the truck back to the shop today. Still getting exhaust through the AC. I intended to take the loaner home and ride the bike to work from there. But their loaner was taken so I had to go back home for the bike and ride to work right from the mechanic. The kids are out of school this week so we can tolerate it better but it's still annoying especially since it was supposed to be finished.

Edit. Mechanic found exhaust leak on the crossover tube that has the catalytic converter, said call muffler shop to fix it since replacing the cat would be expensive. Muffler shop told me to have mechanic check the motor mounts in case that's what stressed it out to begin with. Eeesh, this truck
