Keep refrigerator items from falling

Budward, thanks for the link.  I never thought the problem was big enough for someone to market curtain rods for that purpose.  You would think RV fridge makers would consider "movement" or "travel" as part of their design, but apparently not.  

With my last RV, I had large ice tea cans fall from the top shelf, hit the bottom of the fridge, and actually crack the lining.  I ended up using stick-on kitchen tiles on the bottom of the fridge which helped.  Then frozen goods fell out of the back of the freezer, so I stuck a big sponge back there and it kept the frozen food from falling out.  People would open the fridge and see curtain rods, kitchen tile and sponges and scratch their head!
