I think one issue with container damage has to do with the items that are placed in them. I took chewing gum out of one this week. Anything that smells like food, or is food, or candy, or smelly candles, is smelling like a great meal for some critter. It sure is easier for them than finding a way into your camper to get it. Tupperware to go they say. Try to lug it back to the nest. They probably take out the coins first because they are too heavy to lug. :-)
