When we're not using it, our RV is stored at:
Recreational Vehicle Storage
1354 E Taylor St,
San Jose, CA 95133
(408) 293-4545
We've been there since 1989 and for a spot that holds a 37 foot motorhome we pay about $95 a month. It's fenced, lit at night, and has fulltime on-site managers but it's only open from 8am to 6pm every day.
