Chevy's New Medium Duty Trucks

Thanks for posting that link on the new Chevy MDT. I;ve been looking forward to seeing what they look like, mechanicals, etc. I agree with you these trucks do look pretty good. Will be nice to see Chevy MDT's back on the toad.

nice! I like how the front nose tips forward, much easier to get in there.

I have been waiting for these truck to finally come back out. That means we will be a GM dealer again.

Why the reduction of power rating for the mighty D-max in these trucks compared to 3/4 & 1 tonners?

ford does the same thing for the cab/chassis 6.7, detune and give it a higher engine warranty.

Looks like Ford's 650 destroys the GM 6500 with their GVWR being about 7k higher.

Different emissions certifications and to keep EGT's down when moving heavier loads.

at least the DEF tank will be easy access

I had a 5500 4X4 CC for 10 years. This looks like an updated version of that design. Sits up higher, which is good in my opinion. Anxious to see some interior pics. Looking forward to getting another one.
