Posted this up in the 00-06 forum but figured I'd put it here as well...

Came across the above truck by accident and my mind is messing with me.

Other than some burn oil (which can be remedied so I read with 0w40 oil and Lucas oil stabilizers) and it likes fuel (like all bowtie/gmc suvs) and regular maintenance on the drivetrain, are there any specific items that need to be checked?

Its a good deal @ 179k mi and I can pick it up for less than $9k. I know that GM changed the electrical system starting in 03-06 and that it was much improved over the 00-02yrs.

The burb is all original, autoride works and per the owner, engine was completely serviced @ 150k. Has new tires and a leveling kit less than 5kmi. Burb has every option imaginable minus the 4.10 rear end.

I'm going to look at it next week. I luv my old hoe but did not tow my 5k 23' boat very well. It handled the weight fine but getting going and staying at hwy speeds sucked. The 3.42 rear end combined with no tow/haul transmission doest do the hoe justice. My other 99hoe with the 3.73 rear end towed much better than this hoe but I was just spoiled with the 5.3l and tow/haul tranny in my 07 burb.

The hoe can stay the daily driver as I have a gas card for work and so mpg doesn't matter to me in either my daily driver or my toy hauler.

What do y'all think?

Nothing really different from the 1500s other than what you noted. Look at front end parts (wheel bearings, tie rods, ball joints), and check the transfer case for evidence of oil leaks that could be caused by pump rub. Also check the power steering lines for leaks. They tend to leak where the rubber is crimped to the metal line. The 2500s have hydroboost brakes so there are more lines in the PS/Brake system. It is a failry common problem, but a cheap and relatively easy one to fix.

You won't even know your boat is there. Even just the upgrade in suspension you get with the 2500 would be a welcome change, but throw in the big block on top of that and it will be a completely different towing experience.
