I think the Z71 is the only truck that comes with a Locker on the Axle standard equipment. I have had a lot of Jeeps and was Generally satisfied with everything but the AC, but this new breed has way too much computer crap with no real guts. The Chevrolet has an engine that does seem to pull. The second day I had it, I was forced to pull the Horse Trailer with just one Horse in the Three Horse Trailer but it pulled it fine. I don't like all those auto locking doors but I do like the Thermostat temp control. I bought it for the 4 wheel drive but I hope I never need it. Come Sandbass season that 4 wheel drive will get a test pulling the Mud boat.
You can turn the auto lock door off. there should be a button on the dash that goes through a list of stuff: Horn/lights when you luck/unlock doors, You can set the doors to lock when you remove from park, or after like 15mph and I think there is a third setting. I have all this in my 2009 and lots of other stuff that I don't really need and have never messed with. And yes the chevy dif is supposed to be an electronic locking diff. not a limited slip. Only thing I really don't like is the traction control/stabilitrak, while they are very nice for hwy driving it can be a pain for off-road use. Even when you turn them off, they will still try to control the wheel speed unless you are hammering on the throttle. Not a huge factor for me as this truck is not meant to be baja'ing through that kind of stuff, I have a 93 Toyota dlx for that kind of thing!
IIRC the z71 with extended cab short box is rated for something like 10,000lb towing and 1,000lb payload but all the models(crew cab, long box, 4x4, z71, gear ratio, etc.) have slightly different payload and towing limits. do you have the 4spd or 6spd tranny? Do you know what gear ratio it has? This will make a huge difference in the trucks ability to tow. I refuse to buy one without 3:73 gears and locking diffs.
I have the old trusty 4matic in mine, 6spd was available but pretty new at the time and I just didn't want to go that way until they were out for a few years. IIRC the new ones only come in 6spd now. I pull an 18' bumper camper, and while I do run an equalizer hitch, it is not needed for this size trailer. I run it because they take most of the chuck/bounce out of it and I often forget that I have a trailer hooked up. I can easily pull my camper 75mph down the hwy but generally only drive 65 with it and if the wind is 20mph or more I will slow down to 55. Those campers are like a sail and catch a lot of wind so they seem like they are quite a bit heavier than they are. mine is very very good on fuel pulling or not. at 65mph with 10-12mph wind I will still get 9-10mpg. If wind kicks up over 20 I will get around 8 but in more favorable conditions I have gotten as high as 13-14 towing 70mph. empty I will see 19-20mpg and have seen as high as 24mpg at around 65mph. Gotta love active fuel management!
Im hoping to upgrade to a 2014 by spring time, just waiting for the right deal to come around. Best ive seen so far is $5250 cash allowance for prior GM owners.
BTW: poor gas mileage is just a reflection of how you are driving them!!! lay into the throttle every time you take off from a stop and you WILL loose gas mileage. Driving above 60-65mph will also drink more fuel. there is no way around it. When I push mine 75-80 down the highway I will drop down to around 16mpg. But compare that to my '99 5.3l at about 12-13mpg Also, your truck only has 2600 miles on it so it is not broke in yet. I didn't see above 15mpg ever until I hit the 10,000 mile and it was like I flipped a switch for better gas mileage.
