This is our largest unit. With one inside plug in (110 for trickle charge RV batteries only) and its convenient location, this is our most popular unit. Unique to this location, many people like the extra wide door for storing an RV. The doors on these units are 12' wide and 14' tall. This size unit is great for storing a vehicle, small boat, and various large items with room to spare; or for the contents of a large home while transitioning in a move.
