Self-Storage For a Base Camp?

While I'd love to have my own scrap lot or building, at this point I don't. So in order for me to start hoarding and storing my scrap, are self-storage units feasible? Off the top of my head, it sounds like a good idea (a place to save up a load and/or break stuff down).

Are any other scrappers doing this? And if so, what size unit do you have or recommend?

Thanks!

I did this for awhile before my parents let me use their garage. It helps to have an outside unit, I had one that you had to walk down a hallway.

Also got to know the owners pretty well, they would let me clean out "abandoned" units, and free reign to their dumpster.

I had a 10x10. I mainly used it to store my already tore down stuff.
