Are those people sheepish or are they someone like minded you could maybe trust with those preps and hold some of theirs are your house in exchange?
Could you disguise them as something else? Maybe a hunting buddy who you ask to store a case of ammo at their house and inside that case you store other items?
I store a couple plastic ammo cans at my parnets house with offiste backups and some ammo and gun cleaning supplies. My mother thought the cleaning supplies were making her sick so she moved them from my old bedroom to the garage and then determined it was some silly potpori that was actually making her sick and not my stuff
