Just got back from 2 month trip, which was the first long trip for our cat. We have a Class C + toad. First thing we did was to bomb proof the MH to make sure she couldn't get into the bedroom slide area. We used the "heat" cushions people stuff into the roof vents to keep her out of the very small space on the floor and side of the BR slide. Second we put an old fashioned window latch on the screen door so she couldn't inadvertently push the door open. Once we are at the campground, the cushions come out of the bedroom slide area and are used in the ford cab area to keep her from getting under the dash.
She is always under someone's control when the slides are being moved in or out. We've heard way too many horror stories to take a chance on an accident involving the cat and the slideout.
Traveling was a bit of a challenge for her to begin with. After getting loads of recommendations, we decided to let her have the freedom within the MH (not the cab area) so she could find her comfort zone while traveling. The first week was tough, but finally she settled in and decided she was comfortable laying next to the bed
on the side table under the window and next to the headboard. Her second choice was in the clothes closet. We used our pillows to keep the door securely open.
Lastly, our vet recommended a "calming" spray; Feliway, which we spray in her two comfort areas about 15 minutes before we leave. It is expensive but seems to help.
We do stop regularly to let her comfortably visit the litter box, drink and eat if she chooses.
She is an indoor/outdoor cat at home, but we have been training her to walk with a holster and leash, and she did great on our trip. She was very comfortable at some RV parks and not so much at others. If she wasn't comfortable, she just returned immediately to the MH steps and we didn't force her.
Good luck. We loved having our girl with us and you will too.
