Even though we camp in luxury, we still only use plastic cups/plates/wine glasses/etc for that reason. Plus it makes it feel more like camping, too. All of our heavy cooking items go under the dinette seats on the floor to help keep the C of G lower as well.
If you haven't already done so, line your cupboards and drawers with the rubber mesh matting. It really helps to keep things from moving.
