Boat and RV Storage

Onyx is Here For Your Boat and RV Storage

Onyx Self Storage of Church Hill, located at 121 Old Union Road, provides secure indoor vehicle storage designed for recreational and personal vehicles. Our facility features uniform door dimensions of eight feet wide by seven feet high across all units, making it particularly suitable for motorcycles, ATVs, side-by-sides, small boats, and select RVs that meet these height requirements.


The property offers easy access through wide, paved driveways that accommodate trailers and towing vehicles. Each unit provides ground-level entry, eliminating concerns about elevation or ramps. Our focus on vehicle storage means we've designed the facility specifically for the needs of vehicle owners, from proper door clearance to adequate turning radius in all aisles.

Our Storage Unit Sizes


We maintain multiple distinct unit sizes to accommodate various vehicle types and combinations, ranging from 10x10 up to 10x30 feet. This variety ensures appropriate space options for everything from single motorcycles to mid-sized boats, provided they meet our standard door height requirements.
