Great info. Thanks!

Hey, I have a Facebook group for Mack Fire trucks and a question has come up. I was always told the B model numbers were odd for diesel and even for gas. There is a B-85 that they tell me is gas. It also says Thermodyne on the hood, which I always thought was the open chamber, direct injection diesel. Anyone offer some clarification? I tried researching, but I have not found anything.
