Approximately 400 sq ft of garage space available for storage with ventilation. There is additional space to store items on shelving as well. Additional Side door for entrance/exit for the storage area. I am currently serving in the Marine Corps and live in Temecula CA with my wife. My daily job consists of providing oversight and maintenance to over 20M in military gear and equipment. I can assure you that your storage is safe and in good hands. This is priced low as compared to your traditional storage companies (Extra Storage Space) that will charge $826 for this sq footage. I serve to protect this county why not let me protect your storage too.
