+1 for Corelle. We got ours on sale at Target before we even picked up the trailer. A whole set (for 4) is not all that expensive, and then we have real dishes when we want them. We still keep a stack of paper plates in the cabinet, especially for when we don't have sewer hookups, or when we're eating outside.
Honestly though, we really haven't had anything move around on us. I guess I'm just a good driver
Seriously though, not much moves around in our camper in transit, and for stuff that does, we have tie downs or we "nest" it with other stuff so it all stays secure. Of course, you need to use caution when opening upper cabinets, but that's just a standard rule.
