Had a 2002 z71 5.3 and it seemed to have more power then my recent trucks.
Also had a 2015 4x4 5.3 (not z71) and it consistently got 17.6mpg. Donated to Harvey.
Currently in a 2018 z71 5.3 and get 15.2mpg.
Stock size tires on all.
Its hard to judge MPG unless everyone includes tire size and transmission info. 4x2 vs 4x4 makes a big difference. Even z71 vs typical 4x4 has made more of a difference then I expected.
I will say, Im not sure I like the V8 to V4 switch. You can definitely feel it lag sometimes. Im sure it makes a difference in the gas mileage game though.

The 2500's with the 6.0L I hear is still pretty much bullet proof as well.Originally posted by Artos View PostI think GM's 6.0 is one of the most reliable gassers out there...my tranny crapped out with 335k miles & engine was still going strong.Originally posted by GRIZZ64 View PostMy 2004 Silverado 6.0 has 350,000 plus. Still my daily driver. Still drive it daily on a 140 mile round trip commute.
I'm looking at the 6.0's now. I've been looking HARD at the half ton's but the majority of them are short beds and I need a longer bed, especially once I drop a tool box in it. Definitely need a 3/4 ton truck. The search continues...

Hard to beat any of the LS Chevrolet motors. A couple of years had the active fuel management issue of eating up lifters and then taking everything else out. There is also theory to support that AFM is causing the oil consumption issues as well. Also these motors have great aftermarket support and they respond to modification very well.

You are on the right track, the long beds in the 3/4 tons seem to have WAAYYY more room & you can put a decent size box in.
Good luck, the 6.0 really has a proven record for longevity. Not much in the giddy up department but bullet proof.
