We visited a facility called Sheridan Park Self Storage in Bluffton, SC recently (my husband loves to visit storage facilities when we are on vacation out of state)

Anyway, the office was the end unit in a strip mall, with the resident manager living upstairs. Behind the entire strip mall were 600+ fenced-in units, climate controlled and not, and also RV parking spaces. The gate and driveway entrance were next to the office at the end of the strip mall.

We found it very interesting, loads of parking in front, lots of potential customers going by visiting all the other stores, doctor offices, etc.

I looked for a website, but couldn't find one.
