Does anyone have experience with storing meds/vitamins in a van? I want to know because I may be spending many months in the Pacific NW and moisture will always be an issue. I know about damprid and cracking the windows but there are many more things to consider. Is there some sort of magical storage box that is resistant to moisture and heat and that would work long term? What kind of storage would it be? Both meds and supplements are very important to me and super expensive. I have never seen anyone ask this question here but I don't know of a better place to ask. Can anyone tell me specific experiences they have had and times when they have had to throw medicine away? What tips do you have? What have you learned that might ease my mind a bit?
