Second post. When we had our fifth wheel, we had the pull out pantry spill everything more than once. We devised a small bungee cord affair for plates and such. Still use it in the MH, but short of hitting a wall or rolling over, perhaps, the things in the cabinets stay put and don't rattle.
We use mostly the paper plates, but..if there is a next Motor home it will have a dishwasher and the Chinette will see a lot less use.
The Alumiscape Fifth Wheel we use to have, we couldn't keep the pantry door shut or anything in it going down the road...until we started using a bunch of small bungee cords etc and that was with air ride hitch and shocks. The Mh, I don't think we have had any spills. The plates and saucers are in a rack wife devised with bungees and that rubber stuff doilies or whatever between them and a small bungee at an angle on the rack. i think it just gets in the way more than helps but no rattles.
