i have been tossing the idea of getting a newer diesel i own a 03 duramax now and would be trading that in. just lookin for your input on the trucks/ pros an cons i have driven the lmm an the 6.4 but not the 6.7 cummins. any problems you have had mechanically

 

I would go with the LMM Dmax. The 6.4 would be a powerhouse of a truck just like the LMM, but they still had a few problems with them. Just not a fan of the 6.7 Cummins.

What do you use your truck for, and how much power are you wanting out of it?

 

LMM gets my vote, same reliable powerhouse as the LBZ wrapped in a nicer package, My brother has an LMM and its really a nice truck, it feels more solid, and the interior is quieter than my truck, they are especially nice when the DPF is missing

 

It may just be me, but I prefer the OBS (07 and down) Chevys to the new one. Some of the features are nice, but I swear GM had the most comfortable seats (comparable to an old Caddy or Lincoln) up until they switched to this new body style. Dont get me wrong, the new ones are still comfy, but my body doesnt feel like it melts into the seat as much with the new ones
