2016 GMC Sierra 3500HD SLT 4dr Crew Cab 4WD LB (6.0L 8cyl 6A)
First of all Edmunds doesn't give the Duramax / Allison option to review. That is what mine is so it might not compare to other reviewers. The some of previous reviewers must have been driving a completely different truck then I was. Some of those reviews just didn't make sense to me. This is an awesome truck. It's more "luxury car" like then any truck I've ever driven. And now I have … had 40,000 miles of trouble free use. My wife enjoys driving it because she has great visibility and it is so easy to handle for the "beast" that it is. It easily handles my 39 ', 15,300 5th Wheel toy hauler with a 2 700lb. mototcycles. You actually don't even know all that load is back there.
As it has gotten more miles on it the MPG has improved. I know this is hard to believe but at 40MPH I've gotten over 30 MPG. At interstate speeds of 70-75 MPG it averages over 21 MPG. Pulling my 17,000lb 5th Wheel trailer I get 11.5.
One of the problems for GM is that they build such a good truck that I can’t even consider a new purchase. This truck is all I need and the new enhancements don’t add much to what I already have.
I have had one mechanical issue. A bad injector came up on my “check engine” light. I didn’t notice any difference in performance. Took it to my dealer and the 5 year drive train warranty paid for the repairs.
