I will put this blunt, they burn oil and are known to sear off cam shafts. Personally have seen this happen in 2 (5.3) trucks and 1 (6.0 vortex max) (2007.5-2013 year trucks). Personally drive a 2015 tundra with 162,000 miles, expect 300k before any major repairs.
I thought I remember people having issues with the 5.3 afm turning cylinders off/on causing problems with burning up cylinders. I was suprised to not see anyone mention if before.

That's why I mentioned 5.3 without cylinder deactivation in my post above. I believe the issue has been resolved though.
Here is one way to not have to worry about it, an arm disabled. It keeps it working like the older engines, 8 cylinders all the time. https://rangetechnology.com/afm-disabler/
I have a 2004 GMC 2500HD with the 6.0 It has roughly 250,000 and still going strong so last year I bought a 2017 GMC 2500HD. It also runs great. It is averaging 16+ MPG. I highly recommend one.
