While I've been looking at Ram 2500/3500, a different truck hit my radar. 2007 GMC Sierra Classic SLE dually, 6.6L Duramax and Allison 4spd auto. CarFax one owner truck, with 276K miles. No open recalls/no accidents reported. Dealer asking $17999.What should I be looking for with this truck? It appears to have been very well maintained cosmetically, and it's almost identical on the interior to my 2003 Tahoe LT. You Duramax/Allison guys -- what say you?

While the motor is still mid term, the rest of the truck may be approaching end of life. Front end rebuild, universal joints, wheel bearings, brakes all may need replacement soon.

I would not consider that vehicle. As already posted, most of that vehicle is reaching end of life.

That's a 10-12k dollar truck with those miles where I live.

Thanks for the feedback. While I was hopefully optimistic, the realist in me said it was too much.

So, what are things to look for specifically with the Duramax/Allison combination?

Look for whoever took the other 2 gears. It's a 6 speed.
Given your knowledge or lack thereof of vehicles, specifically, stay away from buying trucks with almost 300k miles on them. May sound snarky but a vehicle like that will cost you several times more to keep on the road than someone who can wrench on their own gear and is knowledgeable about it.

There really isn't much to watch for with that truck. '06 and '07 classic were darn near perfect and highly sought after. That's just a lot of miles. Really any Duramax since the '04.5 LB7 is a solid truck. The '04.5 -'05 LLY don't cool very well but are otherwise very reliable.
