Tampa, FL here - so pretty big area I can survey to include Orlando and Sarasota within 1.5 hours drive.
Snagged a 21 Yukon AT4 last week. It was in transit. Most of the Tahoes in stock didn't have the features I wanted (really only 3-5) and the ones that I did inquire about were sold before they got off the truck.
I guess I got lucky at my local GMC dealer. They had someone drop out of a deal and the truck was in transit. Pick it up tomorrow. Good luck. Most dealers were adding 1-2K market adjustment. I was able to bargain that off but mostly because I was ready to sign the day I walked into the dealership and I brought a trade (Audi Q7). Trade was a little under Carmax but they also didn't knock me on the two real wheels I needed to replace.
Good luck.
