I am looking at buying a 2006 HD2500 with the 6.6 Duromax diesel and an Allison transmission. I drive quite a bit so I am wondering on your past experience with the reliability, maintenance costs and how many miles I should expect to get from this truck.

Wrong forum dude... From what I've heard it's a great engine.
