Well, I don't have any place to put a carrier in the truck, no cover on the truck bed either. But I have lots, lots of bedding behind the seat, then there is other items that is on the top or just behind the seat, so they are protected. When we were rear ended back in 2005/6, Stover, was sleeping behind the seat and he didn't even wake up. Yes, I always worry about them, but they know to stay away from the petals when I am driving. Jim is always with me when I driving, the kids demand, that he hold them, LOL! Marie [Posted in FML 6072]
