[2021] returning player question

You don’t need a base for the sake of trying to explore more buildings with a full inventory. All you need is a secure storage chest. You can put it on the ground just outside a POI: on the street is convenient. Zombies won’t attack these unless you go out of your way to put them in awkward spots, so (in single player) they’re quite safe even without a base around them.

Later, when you’ve decided on a permanent base location and have a vehicle, you can consolidate all these loot stashes.
