We live in a 5th wheel but bought a truck camper to go to Alaska last summer. Our cat spent 5 months in the camper with us on that trip. Here's HIS opinion of our Alaska trip
My Alaska Trip- by DozerHe always goes out on a leash and only when we are sitting outside. It took him a while to get used to it, but he did, because its the only way he gets to go out.
He doesn't care for truck travel much but again, he gets used to it. He is always in a carrier in the truck.
We do keep an eye out for off leash dogs. Dozer is not afraid of them and will actually stalk them, especially small ones, but I don't take any chances.
