2007 Yukon XL Denali Longevity

[tjd3004]

Hello all. I am considering trading my 2005 Z71 Tahoe for a 2007 Yukon XL Denali with 114k miles. I know the GMT800 platform vehicles very well; I also own a 2004 Yukon Denali. My question is about the longevity of the GMT900 drivetrain. I know firsthand if maintained correctly the GMT800's will last 200k+. My 2004 Denali has 331k on the original 6.0, but I've seen some 2014 6.2 trucks that have already had to have engines replaced. Just looking for some experiences, I hate to jump from a truck I know in and out to one I know very little on. Thanks!

Thinking of Buying a 07-14 NNBS Tahoe/Suburban? Look Here

It's basically the same as the NBS. Some people will have issues, but a lot of people are running 200,000 miles with little to no issues

I ended up buying it on Thursday. So far I've been very pleased with it; big improvement over the wife's 05 Z71 we traded in.
