I currently am allowed to fulltime with my owner. He has trained me to protect him, putting him in his crate, whenever the slides are moving, at fuel stops, etc. Otherwise, he trusts my driving enough that he sleeps on the sofa while on the road. Once we arrive at a cg, back in the crate while I setup (he doesn't help) He has trained me to to take him on harness/leash walks around the cg. He knows "let's go home", and heads back to the rv (if he feels like it)He has escaped 2x's in 3 yrs - both times he was so surprised that he just stopped and looked around, allowing me to catch him. He is microchipped. Some things my cat has taught me; try short trips, experiment w/crates/litterbox placements. I have secured my sliding screens with electrical tape, and used door screening to cover open dash access under the driver side. Until you try some rv travel with your 3 cats, you will not know how they will react.
