A guy from a local Detroit/Allison dealer came by our sawmill garage because we ran some Detroits and he had called on us for years. He told us about a Chevy 2500 pickup he had rode in with the new diesel and Allison and praised its power and towing ability. They had it hooked to an enclosed trailer with a lot of weight in it to test. This was a long time before they released it. I knew I wanted one then, but only after a ride in my uncle's '01,(the first one in town) I was hooked. He died last year at 95, and his grandson still drives it. I finally got an 07 new in October of 06. I still have it and love it.
