A used 40ft standard shipping container graded Wind & Watertight (WWT) — dry, sealed, and fitted with functional cargo doors. Twice the length and roughly 1.3× the price of a 20ft, it delivers the best cost per square foot for storage and job sites.

What Cargo Vault Customers Say
Bought two used 20ft containers for equipment storage. Great value, wind and water tight as promised, and delivery was seamless even to our rural location.
We converted a 20ft container into a mobile office. The modifications were exactly as specified and the quality of workmanship is excellent. Highly recommend Cargo Vault.
From quote to delivery the communication was outstanding. They answered every question and the used container exceeded my expectations for the price.
