How to evaluate a used '99-06 1500 for purchasing... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey everybody. I'm about to purchase my first truck (so happy), and I need to get some advice on what kind of mechanical inspection I should go through before handing over my $$$. Keeping my eye on a number of listings, but my first choice is a '06 Sierra with the 4.8L, auto trans, and 140k miles. I know to crawl over the entire thing looking for leaks and rust (I'm only searching in the South and West to avoid rust altogether), as well as jacking the wheels up to push on the wheel at 12 and 6, and 3 and 9 to look for play. Check cylinder compression for sure...but what else? Thanks.
