Looking at 90k and up Burbs for 2nd truck - what would your game plan be?

[TahoeFL2017]

I'm looking at 2017 to 2020 Suburban's and Yukon XL's with the 5.3

Basically need another 4x4 for mostly city driving and some road trips around Florida, and the used ones from the previous gen look like a great value.

I've got 103k flawless miles on my 2017 Tahoe, with the 6 speed. Just AC condenser and a motor mount in the last 80k miles, and AFM has been disabled since 38k miles.

I'm looking at LT's with the 5.3, and wondering what you would look out for - lifter tics, 8 speed trans, anything else?

I see 200k mile rigs online for sale, pretty regularly in the AFM years, so not hugely worried - seems like disabling the AFM and changing the oil before 5k miles keeps them alive.

What would you do?

I plan on buying a 90k truck and if it's 6 speed and not ticking, I'll take it.

Anything else to worry about? Interior, 4x4, electronics, suspension, etc?
Anything else under the hood, besides the AFM and Trans?

Is a warranty worth a damn at 90k miles, or is it only aftermarket warranties and no GM PP at that mileage?
Are the aftermarket warranties worth it or garbage?
Appreciate your input - I'm seeing a lot of clean Burb's in FL and some look immaculate, so my trigger finger is getting itchy!

Go for the 10 speed transmission or look for one that had the transmission already replaced if you go for the 6 or 8 speed. Check the oil pressure and make sure it’s between 25-30 psi at idle.
