We too camp just about every vacation`

etc and have years upon years of scout leadership… If you are taking a pressure cooker or crockpot–you have access to electric.
Buy a dorm size refrigerator/freezer for around $100 and make your life easier. You won’t be able to store tons—but you will be surprised at what you can fit and it will make all the difference. For the dorm fridge– I recommend getting one that has a separate freezer door on top…not inside the fridge.

Just a suugestion.
