San Diego RV and Boat Storage in Grantville has provided secure outdoor vehicle storage at 6996-A Mission Gorge Road, San Diego 92120, since the facility opened in 1957. The gated yard accommodates recreational vehicles, travel trailers, boat-and-trailer combinations, and oversize vehicles that San Diego's residential parking ordinances and HOA rules prohibit from street or driveway storage. A 24-hour security system monitors the lot with surveillance cameras and controlled gate access, and each renter receives an individual access code for entry and exit without staff-assisted scheduling. Oversize vehicle transport to and from the facility is coordinated through Roadway Towing & Recovery in Grantville, which handles fifth-wheel and flatbed hauling for rigs that owners prefer not to drive on surface streets. Mission Gorge Road through Grantville runs north toward Mission Trails Regional Park and connects to the I-8 interchange at Fairmount Avenue, giving stored vehicles a direct freeway on-ramp for east-county desert trips and northbound lake runs. The 92120 ZIP places the lot in the commercial and light-industrial corridor that defines Grantville's Mission Gorge Road stretch, surrounded by auto service businesses, dealerships, and other fleet-oriented operations. Boat owners returning from San Diego Bay, Mission Bay, or the Pacific launch ramps use the I-8-to-Mission Gorge routing to reach the yard without navigating residential side streets with a loaded trailer. Fuel stops before long-haul departures route through Express Gas Mart in San Carlos, positioned on the corridor between the storage yard and the eastbound I-8 on-ramp toward the Anza-Borrego desert. The 1957 founding date makes the facility one of the longest-operating outdoor storage yards in San Diego's east-county corridor, predating the residential development that eventually restricted street-side RV parking across the surrounding neighborhoods.
