Storage containers and storage trailers both give you secure, weather-tight space on site. The difference comes down to two things: how you load it and whether it needs to move. A container sits at ground level and stays put. A trailer sits at loading-dock height and can be hauled away full.

Choose a storage container if…
- You are loading by hand, dolly, or forklift from the ground
- The unit will stay in one place for the whole rental
- You need storage at a home, a smaller lot, or a job site with limited room
- You want a high cube for tall equipment or a workshop
Choose a storage trailer if…
- You have a loading dock and move product with pallet jacks or forklifts
- You need the most space in one unit, up to 53 feet
- You want to load on site and then move the inventory to another facility or job site
- You run month-to-month or annual overflow storage for a plant or warehouse
No dock? Trailers can still be accessed from the ground with a portable dock plate or ramp. Tell us your site setup and we will recommend the best fit.
Frequently asked questions
What is the main difference between a storage container and a storage trailer?
Mobility and loading height. A container is placed at ground level and stays fixed. A trailer sits at loading-dock height and can be relocated after it is loaded.
Which holds more, a container or a trailer?
A 53-foot storage trailer is the largest single unit we rent. Our largest container is 40 feet long.
Do I need a loading dock for a storage trailer?
No, but trailers work best with one. Without a dock, you can use a portable dock plate or ramp.
Can I rent either one month to month?
Yes. Both containers and trailers are available on flexible short and long-term terms.
