I was in a semi-similar situation when purchasing my 2017 TRD OR. I purchased in September of 2019 and vehicle had 65k miles and priced at $32k recently marked down from $34k. Vehicle was used as a dealer vehicle in town, all maintenance done at the dealership, very well maintained.

Price was under blue book, carfax and records verified what the dealer claimed. I had it looked over again, inspected as much as I could, and went with my gut. Sure the miles were high, but it was well maintained and I take pride in my own maintenance. So far no issues with the truck. Granted, I lucked out here where someone else may not. I got a great TRD OR at a price I could afford. No regrets.
