Well guys I cheeped out, went to Infiniti of Scottsdale and found my truck
Ended up with a 2013 Black, Silverado, Z71, 4 wheel drive, extended cab with 39,360 miles on it. One owner, from AZ, and all the service records from new on carfax. 5.3 V8, everything working, not a dent in it that I could find.
They had a 128 point inspection report that shows they installed new tires, turned the front rotors and flushed almost all the fluids, everything else was checked as ok.
$22,500 cash out the door
Still going to have a mechanic look at it tomorrow, but feeling very confident that all is in top shape.
Try to post up a picture in a few days.
