Did the same thing. I knew I was going taco or tremor and shopped a bit. Went toyota shopping in person the day before I ordered my tremor (had always planned on going tacoma route). TRD Pro was ~57k (without title, tags, taxes), 2018 TRD w/45k miles was 48k (without tags, etc.), Off road was going to be 45k. Walked out and didn't look back. Got my tremor for not much more than the new TRD and that with taxes and everything included.
Just couldn't justify not having the additional towing capacity and less space/options at that price point.
