I just got back from a couple of week long trips, almost back to back. On both of these trips there was a lot of gravely rough road driving.
Now the problem: I pack a lot of my canned goods in an older cooler since it helps to keep them from freezing in the spring and fall when my camper is packed but not in use. In it I have regular cans, home canned goods, drinks, and some shelf stable milk. The vibration from travel rubbed the regular cans against the cartons of milk and the aluminum drink cans. Guess which won! Not the milk or drinks. Actually it only holed a quart of milk and one V-8 can, but what a mess! At least the cooler contained the spill. I never even thought about that happening. Learn something new all the time!
Now I have the softer packaged items separate from the cans etc. so that they don't get a hole worn in them.
