well first gen buy fell though so im now thinking of getting a newer truck... first of all any truck i get will be deleted and tuned.. ive been trying to decide between a 6.4 or a LMM. and then the last option is to get a older 2nd gen cummins..

 

My personal preference is the 6.4. I like both the LMM and the 6.4, but I am partial to a Ford! Now, I don't know much about the LMMs but I think they may be a little more reliable than the 6.4. It's all up to you though, of course!
