2006 Z51 4x4 off road extended cab bought new 8/2005. 139k miles in almost 19 years. Garage kept about 80%. Replaced front wheel bearings and heater core at 50-70k miles. Two sets of tires, one set shocks, one set front & rear brake pads. Oxygen, oil pressure sensors and lower driver seat cover at about 125k. No corrosion in a southern state. Paint and trim almost like new with regular maintenance. Mostly light road use sometimes loaded with heavy cargo and occasionally on terrain at the farm hauling trailers around on dirt trails. Good off road too. Best vehicle I've ever had and will never go out of style. When getting supplies, people at the co-op have asked what year it is and are amazed.

I bought a new 2006 1500 crew cab Z71 and it lasted 18 years. Great truck for the time it was built, extremely reliable. I don't think any new truck could be as reliable as this has been. It has over 180k miles, original engine, trans, exhaust and many other parts. I've only changed oil, brakes, radiator, alternator, starter, and power steering pump. The front hubs have been replaced a few times. Hubs are a common replacement item on these trucks. The 5.3l engine and 4l60 trans have been amazing. I've towed and hauled over the rated limit several times with no issues. Its a Northeast truck so rust is becoming a problem. I probably should have found a rust free 3500 instead of buying a new one.

u could take the engine out of this thing and throw it into the atlantic ocean, fish it out 30 years later, then fill the gas tank up with peanut butter and it would start right up. u cannot kill this truck. it will outlive you, your kids, and your grandkids.
