I believe the father said he thought Deorr would be fine with his ggp by the campfire. I assumed that meant little Deorr was not in the truck by the campfire, but I may have interpreted his comments too narrowly. I don't understand why his blanket was in the car if they had set up camp next to the fire. Wouldn't they bring out all the things they needed, at least for Deorr's impending nap? (blanket, cup, monkey...)
We don't even know they set up a camp, do we?
