We had mirrored glass fronts on some upper cabinets on the side of our old 2003 Prowler TT and I added a shelf in the middle to make more storage space and that's where we stored our canned goods and such.. We put the cans in baskets and then put some of those spring loaded bars between the opening and never had those mirror fronts break out in over 16 years of use.. Went over some rough roads too.
We also put down that rubber mat stuff on the shelves and that helped a lot with movement of the stuff too.
Good luck!
