The owner of the LMM 2500 reported that his first tank of fuel produced 17 mpg while running at Interstate speed across Montana. This owner has owned a number of Duramax powered trucks prior to this one, his LB7's would produce close to 20 on the same trip, and his last Duramax (a 2005 LLY) struggled to produce 15. So, he's happy with the LMM... so far...

Keep us/me posted I ordered the new body sierra LMM 3500 SRW SLT 4X4 long bed and hope to get it by the end of May.
Anything has to be better than the 6.0 disaster I had.
I know it is early reports but "Thanks for the info".
