Was looking for a truck just like Hack's, but ended up settling for a smoking deal on a (smaller?) truck:
Just took delivery on Friday. 2018 GMC Sierra 1500 SLE, Regular Cab, Standard Box. 4x4, Z71, 5.3L, 3.42 axles, and every option I could get on that model:
I almost sprung for the Borla Touring cat back. Decided that a grand was too much to spend. May still get added in the future.And the 5.3 sounds a LOT better with a cat back system
I like it so far. I drive 60 miles round trip to work, and driving carefully I average over 26 mpg on the computer. 3.42 gears, 8-speed automatic behind the 3.6.
I've looked into the chips, but that'll have to wait until the basic warranty is done. I didn't opt for the E85 option. But some of the chips will allow for a 92-93 tune.Throw a Hypertech chip in it and love it even more.
If yours has the yellow gas cap, add e85 and HP increases by about 30 as well. Mine was not e85 compliant so I couldn't do that, but still was impressive.

The first tank of gas, I averaged 25 mpg (on the dash computer) for the tank. Combination of city/interstate driving. Which is about 9-10 mpg better than my 2002 Blazer with the 4.3L did. If I can keep it at 55-65 mph, the mpg is fabulous. All that starts to fade once I'm above 65 mph or something is on the hitch ball...
I really considered getting either a Colorado or Canyon (I wanted the diesel), but my son talked me out of it. The short wheelbase of the Sierra I have made it easy to get the boat and pontoon into the driveway without driving up over the neighbor's grass. And for the most part, it's just me in the cab.

I put a K&N kit on my 15 250 and although it did help mileage, the noise when running hills towing drives me nuts. Don’t get me wrong, I love loud exhaust but with the intake being basically in your face is a bit annoying.
