Travling with a TC and a cat

We routinely travel with the cat. I made a boot between the camper and truck window, mostly he likes to travel in the cab but he will change his mind from time to time. When we stop we can push him through the window into the camper and shut it so we can open the doors in traffic etc. without worry.

I even added a bathroom for him: cut a cat door through an inner wall and dedicated an outdoor accessible compartment. Easy to service, out of sight inside.
