Oo. I just got back from Michigans Upper Peninsula where I spied some Dodge boys testing out some Cummins equipped trucks. I spotted them in a Marquette Holiday Inn parking lot at 5AM Monday morning. So I turned around and did what any TDR member would do. I did a little spying. There was approximately 7 Cummins powered trucks. Every combo you can think of. Short bed, long bed, Standard cab, Mega cab, 2WD and 4WD. 1 Powerwagon. 1 Dodge Sprinter van(white), and 1 Chevy Duramax. The reason I say they all were together is they all had numbers on back of window (1-9) and had manufacture plates, except the Chevy. It had regular plates but a number in the window(8). They were all black. No badges. Back to the good stuff. I crawled under two of them and this is what I saw. No V-8. It was definitely a Cummins inline six. Whether it was a 5. 9 or 6. 1 who knows. It was a Cummins inline six. As far as the transmission. It was not the new 6 speed offered up in 06 models, that is for sure. I just went to our dealer here in town on my way home and looked at 2 of their six speeds they have on the lot. Totally different ! I could not tell you what it was. It did have a temperature sensor coming out of the bottom. I couldn't tell you if it was a stick or auto. I guess I should have looked in the window right? Maybe it was the rumored Aisin 6 Speed Automatic! Oo. Whatever it was, it looked beefy. I wish I had my camera I would have snapped photos underneath everywhere. UGH! They all had square diesel tanks in back of the beds, with pumps. They also had something running. As I walked up to them, I could hear what sounded like a furnace or hot water heater power vent. I couldn't tell where on the vehicles it was coming from. The clerk at the front desk said all she knew was that they were cold weather testing. I just thought I would share that with you all.
