About the units

Our units are clean and come in a variety of sizes to fit your storage needs. Drive right to the door for easy loading and unloading — you are not carrying a dresser down a corridor or waiting on a lift. The yard is gated and fenced for your security and includes a computerized keypad gate for easy access. If you are moving a trailer or a rental truck in, the 10 X 30 with double garage door gives you the widest opening we have at $145.00 a month.
