Agree on the pretty much bullet proof drive train with a caveat. That transmission tends to have issues shedding heat when working hard pulling grades and decending in lower gears, especially pulling a trailer. I have a trans temp monitor and have occasionally had to pull over to keep the trans temp from climbing.
I have the 5.7 engine with a nine blade(yes, 9) fan on it. I replaced the fan clutch and the heat shedding improved but still an issue, especially in warmer ambient temps.
In looking at this unit, pay a bit of attention to the condition of trans fluid and trans behavior. If you buy it, I would suggest replacing the trans fluid with Dexron VI if it has not been already done. This fluid is quite a bit more heat tolerant and may help the trans run cooler.
