I ended up lucking into one at MSRP that pretty much checked every box in the 'need' category at a dealership 5 minutes from my house. They wouldn't take reservations or holds, just happened to be able to get there quickly whenever a truck rolled in with Tundras on it.

Another dealership offered me a TRD Pro Tundra, with a $16k dealer markup. I passed, but from what the salesman told me later the very next person (I was #1 on the list) he called bought it with that markup without hesitation.
