Was having problems with my 19 TB, originally wanted the 3.0 when I bought the TB but wasn't available in 19 and still isn't in the TB. Got tired of all the problems with the TB so decided it was a good time to try the 3.0 and the 10 speed. Ordered a LT with convenience package ll, Z71, bed protection package, all star package, advanced trailering package, safety package, side steps. No fog lights available from factory on the LT so I had to add them. Put on some dura traks which cost me 3-4 mpg. So far very happy with my purchase.

They do warm up nice while driving but if you are setting idling it will run on the cool side. I also changed tires, went from the factory so called A/T Goodyear Fortitudes to Duratraks and lost about 4-5 mpg. Nice to be able to get around in the mud without spinning and sliding around. Still averaging 25-27mpg on the highway. Loving it so far at 2800 miles.

So the truck is doing well, I put on some AT tires, we go camping and most of the time its off the beaten path. The temps here have drop to low 30's and I have found it nice that it warms up fast. My other Duramax (6.6) would take forever.

I don't have a 3.0 have been waiting years,years and years for something like this and I think GM nailed the combo! Tell me what your impressions are.....Thanks!

Got this driving around this morning scouting. most speeds were anywhere from 20 mph to 50 mph on back roads.

Ordered one back in November, just picked it up yesterday, dic was showing 29.5 mpg for the short 25 mile drive home. Liking it very much so far

So I'll start this off. why did you get your truck with a diesel in it? What do you plan to use it for? Post a pic if you have one and fill us in on your options.

I just picked up a 2020 Sierra SLT with a Duramax 3.0L motor a week ago. The truck performs better than my expectations. Initial fuel overall use is averaging +/- 25 mpg. Motor is very quite and the 10-speed transmission is seamless. Looking forward to towing my travel trailer next week.

great, let us know how it goes when you get it!

"Built" and placed an order for one a month ago as I couldn't find anything near MN (summer) or AZ (winter). Replacing 2014 dble cab 5.3 with 75k miles. Any info anywhere on production scheduling?

I just picked mine up 2 weeks ago, I did have the 2.8 duramax but wanted more.
