However, if you need a modified container for a specific purpose, we can quote your delivery from our Phoenix location, where our modification capabilities are greater.
Rest assured that you won’t be charged extra just because we transport it from Phoenix: You will only be charged for the delivery distance between our Tucson branch and your location. We use our company network to make sure that you can receive a high-quality product for a competitive price.

How to Rent, Buy or Modify Containers in Tucson, Arizona
1. Consult with a Container Sales Expert
Your first step is to have a conversation with a sales representative. They’ll guide you through the process and can provide you with a quote. Their expertise allows them to assess your specific needs and recommend the ideal container size and type tailored to you.
2. Prepare the Container Site
Once you’ve settled on the perfect container, it’s time to prepare its designated location. This preparation might involve clearing the area, ensuring a level surface and confirming that our delivery truck can access your location. A properly prepared site ensures the safe and stable placement of your container, smoothing the delivery process.
3. Receiving Your Storage Container
After completing all the necessary preparations, it’s time to receive your storage container. We try to provide advanced notice before delivery, helping you plan around our delivery.
Whether you choose to buy or rent, these steps will ensure a smooth and efficient process, ultimately giving you the peace of mind that accompanies hassle-free storage.
Touring the Container Yard
At Southwest Mobile Storage, we know that it can be difficult to part with your money if you haven’t seen a container in person. Nowadays, shipping container scammers are prolific, and they want to get their hands on your money any way they can.
While you don’t need to see a container before you buy, it can help you better understand the container’s quality. If you’re comparing two options, nothing beats talking with a sales representative in person who can show you how different containers can serve your needs.
Feel free to visit our location between 6 a.m. and 3:00 pm, Monday through Friday. Give us a heads-up before your arrival, so we can welcome you appropriately.
