Mods, feel free to move if this is not the correct forum. I am looking into the idea of using airtight tubs to store dry goods in, underneath my trailer. Things that will not be affected by freezing temps, like flour, sugar, salt, etc. I hate to see all that perfectly good storage space go to waste. What foods can I safely store under my home? I already have some tubs of off season clothing under there. Any other ideas would be welcomed. Thank you.
