69project if you are located anywhere near texas get a nelson tune so if you want to you can get him to street tune it which will be a better tune than just a mailed tune. Get CAI exhaust and a tune and its hsould bring you up to the mileage that you want.

Thanks in advance.

The rear axle in the 1500HD is a semi floating 9.5" 14 bolt and in the 2500HD is a full floating 10.5" 14 bolt. The frame in the 2500HD is a little different as well. The 1500HD frame narrows from 8" down to 5" over the rear axle. The 1500HD is rated at 8600 lbs and the 2500HD is rated at 9200lbs and the towing capacity is higher as well.
I saw 12.5 mpg over the winter and will see 13.5 to 14 over the summer with a highway average near 16 mpg. Towing a 5500 lb bumper pull trailer I get 9-10 mpg.

HUGE clutch fan. hehe.
i have a std cab 2wd LS. beating the heck out of it, i get just under 12. driving normal, 12.5-12.9. being very easy on the foot, i got 14 even.
the truck is bone stock. i plane to do some things mentioned to help with the milage. my old 1500 vortec truck only got 15 or so, so im not down much, and the power difference is worth the loss in milage.

I have a '03 Yukon XL 4x4 w/ the 5.3 and it gets 18-19 on the highway, with 3.73's. Around town is 14-14.5. I wouldn't think 35 more cubes would make such a big difference. I am guessing a crew cab weighs about the same as my Yukon XL (5200+), but maybe I am wrong.
