Wait, so the $850 one already had the tow built in the whole time? You weren't running quotes backwards, you were just comparing prices when some of those prices didn't even cover the same thing. A $600 quote that can't touch a dead car and an $850 quote that includes a tow are not the same service, so lining them up cheapest to priciest is kind of apples to oranges. The dispatcher didn't really prove you had it backwards, she just got you to ask what each price actually got you. I ran into the same thing when a car of mine wouldn't start, the low quote was pickup only and I had no clue it worked that way.

Pulling early is the real trick, temp is only half the story. I do 380 on thighs and start checking at 20 minutes, they hit 175 to 180 and stay juicy. Carryover cooking keeps going after you pull them anyway, so yanking them a few minutes early is doing more than people give it credit for.
