You didn't look to hard obviously - it at all - because the Motor Trend Death Valley off-road review, (48 Hours In Hell) is clearly available. ?It is a complete review off-road in Death Valley during the summer for two-days against the Cadillac Escalade, Ford Explorer, GMC Envoy, Jeep Liberty, Nissan Frontier, Toyota Sequoia, Chevrolet Silverado HD, which the Avalanche received rave reviews on its ability.

There is another story in the Award section where Canada awarded the Avalanche truck of the year - shoot the darn picture they took the Av's got to be on a 20 degree incline in mud...again on the links page...

Here is an updated URL to the Northwest Mudfest - that the Avalanche won...

As far as owner reviews they aren't biased - there are pretty frank and there are a fair share of complaints.
Actually the more I think about it, the more this thread feels more like a troll because the information you're looking for is clearly here...
Well, with the greatest respect, Chief, I think you're a little off the reservation here. I took the time to track down all the references. And the Death Valley one was VERY hard to find (your URL does not work), but I eventually got to it. And it wasn't exactly a review of offroad performance, nor, apart from extreme heat and spectacular scenery, is Death Valley a hard-core off-roading mecca!
Let me also quote an earlier reply in this thread:-
"How is it off-road? I dunno yet. Approach angle, departure angle, and overall wheel base are not what you would hope for in a true rock crawler, but then that wheel base sure is nice when you pull back on the pavement. For trail riding (which is what you originally asked about) I would say it would be a worthy ride. "
I also own, and offroad, a '98 Jeep Wrangler. I just bought an '03 AV Z71. I got the Z71 package because I am going offroad in the AV, but I am NOT 'going offroading' in it.
"Approach angle, departure angle, and overall wheel base are not what you would hope for in a true rock crawler" Hey, I am all in favor of not abusing something for not being what it does pretend to be, but that's rather more than somewhat leaning to the 'innoffensive'.
Approach angle, departure angle, breakover angle, width, length and overall wheel base are ABYSMAL for a true rock crawler. The Avalanche will never be a 'serious' off-road vehicle. Even with a six inch lift (huge for a Jeep lift, for example) it ain't gonna make it through the first obstable on any 'moderate' trail and it might not make it TO the first obstacle on severe trails.
Don't get me wrong, I love my Avalanche, and it can probably (haven't tried it, yet) safely and comfortable go fast and fun on fire-roads and logging trails that would have my Jeep throwing itself off the trail into the shrubbery at thirty miles an hour slower! (I mean that literally, by the way. My Jeep would not control the ride sufficently well at even moderate speed and would be out of control).
The kind of offroading that I do in my Jeep takes place at 1 to 4 miles an hour with experienced spotter(s) and hand signals and multiple re-tries, and often body damage. (you have to not care about the body damage

)
From what I've seen and read on this thread, the AV owners that are having a blast offroad are doing a VERY different kind of off-roading' than I think dmacker is talking about.
The AV is MUCH better than the Jeep for that, and I look forward to doing some.
The AV is UNBELIEVABLY better than the Jeep on-road.
And it gets about the same gas mileage!

But for what a lot of people would regard as 'serious offroading' e.g Tellico, Moab, the Rubicon, even Land Between the Lakes, the Av is the wrong vehicle.
There are a number of other vehicles than Jeeps that can be modified into serious offroaders, but it would not be wise to start from an Avalanche to get there.
