There’s this notion with many of these solutions that we could rent a few hours from Yellowstone, the parents could get up at the crack of dawn and drive while the kids sleep. Wake up kids, that’s Yellowstone up ahead! But most of these contraptions specifically warn against operating them while occupied. They aren’t built for accidents.
Community has an episode at the end where they trash a camper. It seemed comedy driven at first but the longer I looked at it and campers the more plausible that scene seemed. It’s foam and plywood.
Edit: I finally clicked through the autopian link from up thread and it’s reminding me there’s a guy I watch sometimes who does conversion vans. All of his stuff is built around those extruded aluminum rails. He hasn’t figured out how to make use of those last few cubic feet yet but he seems to do a good job and they’re fairly sturdy. Last I watched he was perfecting his showers.
I now wonder what it would look like if he converted buses instead of shop vans. You have a superstructure that might actually survive a hit, they’re already set up for AC units, you “just” need to build repeatable interiors. But you need much more shop space, time, and capital to do something of that sort.
