Not to discourage anyone and it was probably a fluke, but my 2016 2500 HD was sitting inside the heated building this weekend- fire extinguisher mounted on the crew cab back wall. We came in this morning and it looked like it snowed inside the truck- no idea why, but the extinguisher decided to explode over the weekend! One of my employees spent almost an hour with a vacuum, cleaner, and rags to clean it up. Never happened before, may not again, but makes me think twice about leaving one inside my car unattended. Honestly I should have taken a picture- it was crazy!
Working on old cars teaches us patience... and every curse word imaginable!
