Differences between 1500 and 2500 MPG (gas)
I am in the market for a 1500 or 2500 gas motor GMC or Chevy ECSB in the 02-05 range. I am mostly looking at extended cabs and crew cabs. Go easy on me I am a Camaro guy and am getting rid of my Ford to buy GM so I am not well versed in the GM trucks. I know that I can get a 6.0L in the 2500 and a 4.8 or 5.3 in a 1500. What are the major non-cosmetic differences between the 1500 series and 2500 series? Is there a big difference in weight? Is the 6.0L really worth the upgrade from a 1500? What is the difference in MPG I can expect between a 5.3 and 6.0? I would really like a diesel but the budget most likely won't allow it. Thanks in advance.

If you don't plan on towing, just get a cheap 1500 w/ a 4.8 and then drop in a 6.0. Easy as pie.
The frame on the 2500 is going to be beefier, bigger brakes, bigger rear end, and you'll get the 4L80E behind the 6.0 which will make it feel like a dog off the line due to different internal gearing.
2500 6.0 only get about 12-14mpg if your lucky.
My 03' with a built 6.0 got around 15-16mpg, if it was a bone stock 6.0 I probably would have got 17 or so.

my 05 z71 had the L33 5.3L and 3.42's with 33's on it. Hwy - 20-23 MPG, City 14-17 MPG.
06' VMAX 4wd, LQ9 6.0L and 4.10 with 33's. Hwy and city 12-16 It doesnt matter I get shitty mileage, Except at 35mph I get 24MPG, so yes I drive slow now.

Yes you will get much worse gas mileage, but again that is due to the 4.10s and the numerically higher overdrive ratio.
The 2500hd is a much more stable truck. As said, the 14 bolt and 4l80e are very strong and can take a lot of abuse. The interiors are identical. You benefit from the larger engine,transmission,rear end, frame, brakes, hydroboost brake setup, and a few other things I'm forgetting.

I agree, but only to an extent. Yes the 4l80e is geared numberically lower than the 4l60e, but the 4.10's make up for a great deal of that.

Can you get the Allison with a 6.0L? I thought it was only available on the DMAX and maybe the 8.1L. I am leaning towards a 1500 at this point. I tow occasionally and my truck bed stays empty 90% of the time. A 2500 would probably be overkill for my needs. I would love to have a 5 speed auto though.
