Used Mobil Storage Containers and Vaults for Sale. We have clients in TN, MI, PA, FL, and CA that want to sell used wooden storage containers or wooden moving vaults. Typically these containers or vaults are 5'x7'x8' and are in good condition. They sell for $100-$200 apiece depending upon quality of construction, age, condition, etc. These assets would be a nice fit for a self storage operator expanding into the portable storage or moving business.
