I have 10 x 30 and 11 x 16 storage units I rent. I have rented various units there for about 10 years. I don't store any guns or ammo there. One unit has a gas powered pressure washer (with stabilized gas in it), 3 generators (all with stabilized gas in them), about 100 - GI 20 mm ammo cans and several empty gas cans. I don't know about any "explosives trained" police dogs sniffing around but I've never had any problems with anyone saying anything about what I might have stored. By the way the other unit is where I store my lawn mower during the winter. Used to be called Mini Price Self Storage but all were bought out recently and renamed Extra Space Storage.
