You think I can get away with it not being climate controlled if only for a month?
No.
EDITED because I'm awake now, had my coffee -
You could probably get away with storing a couple firearms in a non-climate-controlled space if you thoroughly oiled/greased all the metal parts and stored them in a sealed container with dessicant. But it's chancy. The problem is that as temperature changes from cold to warm, you get condensation - and condensation is bad, it brings on rust. Rust brings on pitting.
When I stored Steve's guns, the unit was heavy screening; you could see into each unit. I loaded the firearms into non-descript boxes and stacked them, then tossed some crap on top of them so that they didn't look valuable.
The unit that I used while I was summering in CT was carefully chosen. It had no external access, you had to go inside a building to get to the door. The door was a rollup garage type, nothing to be seen from outside of it. Their internal cameras could see the hallway, but not inside my unit. I was extremely discreet bringing in the safe, (we wrapped it in moving blankets, so that it just looked like a big box). I never opened the unit with anyone else in the hallway, so nobody saw the gunsafe, the shelves of ammo or anything else in the unit.
That was a 10x20, climate controlled, restricted access. Nothing extraordinary, you ought to be able to find one similar in or near your town. That one cost me about 325 per month. I just looked at that cost as part of the cost of maintaining a camper in CT while living in GA.
