Punkin loved the truck. As far as he was concerned, he had two houses; one big quiet one, and one little noisy one. He always was ready to meet new people, see new things. He rode a lot of the time in the map shelf we had beside the driver's seat, so he could sleep and get petted.

Looking out for trouble
Asleep on the seat
Asleep on the map
When we were at home and getting ready to go to work (we left Tuesday morning and made two round trips to Phoenix every week, finishing up Saturday morning), we'd open his carrier and he would climb right in. The same way in the truck when we got done for the week.
He DID scare us by jumping down and taking off a couple of times. We don't let him outside, because he has no sense about outdoor safety.
