If you're still looking, I have a 2021 Double Cab, SR5, 4x4 with the TRD Off-road package, 38-gal tank, bed liner. It Magnetic Gray, and has 27K miles.
Has a small scrape at the bottom of the right rear door, otherwise it's in great shape.
Non-smoker, and no wet/muddy dogs inside.
I'm in NW Colorado, about 9-hours away from you.
I took the step bars off and gave them to a neighbor who has a Tundra.
