Hey Scotty - I am considering buying a 2002 Chevy Silverado 2500HD 8.1L Vortec which also has an Allison transmission. It has 131k miles. I'll use it for local driving and plowing my half mile long driveway. I've been reading, and have been told by quite a few car enthusiasts, that these are reliable trucks and that the engine and transmission combination is "bullet proof". Is this true? What has your experience been with them? Thanks.
As of my knowledge of that particular model, it is a very reliable and strong engine. Especially if you have that Allison transmission. Those things are work horses. A lot of hp&torque, and was meant for a heavy duty truck. Now the difference between GM trucks, the 1500HD GM trucks are made in Mexico, with less quality control (made there cause labor is cheaper & quality inspections are approved/disapproved in Mexico). The 2500HD GM trucks and above are generally manufactured in Fort Wayne assembly plant in Roanoke, Indiana. Which have been known for making decent vehicles, with decent quality control. The only thing concerning me, is make sure the maintenance records are all done. Any engine can hold up a decent amount of time if we’ll maintained (some engines last longer than others). Though as long as those maintenance records look fine than from my knowledge that vehicle should last you a decent amount of time. Maintenance is key to anything lasting a decent amount of time, THOUGH it is ESPECIALLY IMPORTANT for more powerful engines. Due to more power = more ability to do things. For example, if two people owned the same truck, but one person towed heavy amounts of weight for long distances and the other person just drove it as a daily driver from home to work, with little to moderate towing (since this is America and lots of people just own trucks for status & appeal rather than practical functionality) the second person would have a longer life in the truck; more strain more pain. Though just make sure you stay on top of maintenance but if it has been taken care of and not abused from what I know that truck will last you a long while. Good Luck!
Kind Regards,

Even when abused and not well maintained, these were very simple, well made trucks made as trucks, not 1/2 ton Mommy wagons masquerading as a pick up truck. No VVT or AFM to worry about.
The powertrain should be fine with 130k.
I would be more suspicious of the the body, electronics, accessories etc. on a 20yo truck.
