I liked the comment that the guyy said the salesman told him that GM fixed the problem??

The lift and tires (without regear) is not helping anything, but there are a few others, that were stock, chiming in saying their temps climb too. O'boy

Na, not as bad as an LLY, but still a concern.

Sounds like the LBZ to me (which is what the LMM is basically)
It can keep itself from OH'ing but it uses the fan a lot to do it. Most people won't put the right combo together to ever realize it though.
