We have taken 2 cats in the truck quad cab. There was room for a litter box behind the drivers seat. One would lay on the centre arm rest just to piss the other one off so she could not get into the front. They would both usually settle down on the back seat after a while. One would use the litter box within about the 1st 10 min.of driving. Now that our daughter doen't camp with us she gets to take care of them. One of them has been coming out to the camper when I'm in there checking things out & wants to come in. He looks around & I think he would like to travel again. He enjoyed being tied up and out at the camp sites. The other would sit at the camper door & look out all day but would not go out.
