I have put a nine footer in my garage for the same reason, no room. Humidity here is a killer too. Get a De-Humidifier, Air Conditioner and a heater. I mounted shelves above shoulder high for box storage. When the heat is high and I go out of town for a while I just turn the De-Humidifier on and it creates an atmosphere like being in southern California. (Nothing rusts in California) A couple of hidden mouse traps helps. They will try to set up camp with the new climate. I don't run the De-Humidifier and the Air Conditioner at the same time, it is one or the other. I refer to the garage now as the Pool Hall and I couldn't be happier. Good luck. I couldn't have made the decision at a better time, the local Pool Hall has recently closed.
