Re: Keeping food in my bus this winter.
what they said^^^^.
A can may or may not have flexibility enough to survive freezing, but, if they do, you probably won't want to eat what's in them next summer.
Here's an idea. FInd out for yourself. Put a can of something in a ziplock bag and put it in the freezer for a few days. If it pops, the bag will contain the mess. If it doesn't pop, take it out, throw it in the fridge for a few days, then back to the freezer. After repeating this cycle a few times, attempt to eat it. I predict that it will suck.
I would recommend that you round all that stuff up in a container, bring it in the house and use it.
