It seems like maybe they could be mounted in a two-part rocking carrier, with a weight at the bottom of the fridge itself. It'd be a bit bigger and heavier, but it would allow safer operation of the fridge. It'd probably need to be lockable for driving, though. They may even make fancier models of fridge that can be safely operated on a bigger slope, I dunno. My RV is actually a pretty low end, bare bones, model. All of the accoutrement is toward the cheaper end of the scale. The big diesels tend to be decked out with the nicer kit.

They've also gotten a bit better at surviving sloped operation; modern ones can be operated while driving and for short periods parked on a slope. Older ones were more sensitive.

Also, sleeping on a tilt is uncomfortable. So, leveling is kind of useful for humans (and dogs), too.

RV's usually have these things attached so that they don't move around while you drive.

> Why don't they just tilt the fridge?

Reminds me of the joke about the engineer: "hey, why can't those blind guys just play at night?".
