I towed a 28' footer with 02 Z71, the tranny and engine did excellent. What I didn't really like was the soft rear suspension, althought that could be fixed with air bags.

I just picked up an '04 Avalanche 2500 4x4 2 month's ago.
I was specifically looking for a 2500, and they aren't that easy to find,and when you do, they seem to go pretty quick.
I'd been searching for several months before I found what I was looking for.
I've got the 8100 in it and 4WD, I'm not sure on the gear Ratio but pretty sure it's the 4.10:1. Which makes me good for 12K.
If it's only the 3.73 ratio, I'm still at 10K - which is way plenty for my rig of a 24x7 Pantera.
I bought the truck thinking that I'm not sure what I'll need to tow next - it never hurts to have too much truck.
I do have to say, I absolutely love the truck.
And, compared to the newer ones, the body changed to something that doesn't look nearly as tough. It's become a soccer-mom truck in the last year or two. I parked next to a new one a week ago, and it just looked like a toy next to mine.

You are correct, 2500 3/4 ton option no longer available. Only options are 5.3L vs. 6.0L, 2wd vs. 4wd & 3.73 vs. 4.10 (not 4.11).
I've been towing my 30 Skater locally to the ramp (approx) 6 miles figuring if the boat weighed 6700lbs dry the boat & trailer might weigh 8500lbs. I was way off. I towed to a truck stop & dropped the boat & trailer on the scales, much to my surprise she weighed out @ 10,950 1/2 full of fuel. The auto leveling suspension is deceiving as I'm way over. Ordered a 6.0 gas 2500HD Crew Cab w/ 6spd auto w/ 3.73's.
I believe wheelbase & LT tires make the biggest towing difference from a weight handling standpoint. Tahoe has a pretty short WB, an Avalanche is equal to a Suburban (which is still available in a 3/4 ton).

I have an 08 Avalanche and an 02 2500 Duramax Crew Cab. The Avalanche is fine for close by flat ground towing, but I towed my 28 Advantage up to Lake Hartwell this spring and those rolling hills on I-26 just killed it. It was down shifting on every incline. It handled fine, but just no comparison to the 3/4 ton diesel when it comes to overall power. Also the 3/4 ton braking is far superior to the 1/2 ton brakes. Same trip with the diesel, and it never once came out of overdrive.

BAJA, you can get a 2wd z71 tahoe in 05 only. I guess it wasnt for offroad just more of an appearace package. But traditionally all z71's are 4wd. Just ended a career as a buyer for "the auto superstore"-tons of useless knowledge.
correction 05 and 06

Close. I have an '05 2500 4X4 with 8.1 and 4.10 gears. I'm pretty sure '05 was the last year of 2500's.

Look at the build sticker in your glovebox.
Look for GT4 or GT5
GT4 = 3.73
GT5 = 4.10
