Check out my blog here on BP called "All Things Self Storage".....I think it will give you a decent overview. You can also message me if you'd like and I can give you a few more resources.
You should also search "self Storage" as a lot of threads have info I think you will find valuable. Lastly, be sure to set up "self Storage" as a keyword alert so you get notified when others mention it here on BP.
Thanks Mike I will look in to it.
