I believe they have the 900 square foot units listed on Craigslist for $490 per month. You can see a pic of them by going to safestorage.com, click on "what we offer" and click on "personal warehouses". They are very nice and secure units complete with security gate and 24 hr camera monitoring. I love it, I can back my boat and truck in, close the garage door and still have a few feet in front of my truck to walk around. They are also insulated and have heaters for winter storage, ceiling fans for summertime. Ceiling height is probably close to 20 feet high. I think they were designed for people to park big rv's in.
