Frequently Asked Questions

We carry 10-foot, 20-foot, and 40-foot shipping containers. The 20-foot is our most popular size and works for most residential and commercial storage needs. The 40-foot is ideal for larger job sites or high-volume storage.

New containers (one-trip) have only made a single ocean voyage and are in near-perfect condition. Used containers show surface wear but are still structurally sound and watertight. For most storage applications, a used container is a great value.

Yes — it's one of our specialties. We deliver across Montana, Wyoming, and North Dakota, including rural properties, ranches, oilfield locations, and sites that larger companies won't touch. Call us with your address and we'll give you a straight answer.

Pricing depends on container size, condition (new vs. used), rental term, and delivery distance. We don't post fixed prices because every situation is different — give us a call or submit a quote request and we'll get you an honest number quickly.

Yes. Ask us about applying rental payments toward a purchase.

Yes. All of our containers are wind-and-watertight with a standard locking door. We also offer containers with lockboxes for added security.

We offer office trailers, on-ground offices, modular offices, and office-storage combination units. See our Mobile Offices page for details on each type.

Permit requirements vary by city and county. In many rural areas, no permit is required for a temporary unit. We recommend checking with your local planning office — and we're happy to help answer questions based on our experience in the region.

As long as you need. There's no maximum rental term.

Most of our refrigerated containers (reefers) run on 460V/3-phase power. If you don't have that available on-site, we can pair the unit with a generator. Let us know your site setup and we'll recommend the right solution.

Our refrigerated containers can hold temperatures from approximately -20°F up to +70°F, making them suitable for frozen goods, fresh produce, beverages, and temperature-sensitive materials.

Yes. We offer short-term rentals for festivals, catering operations, outdoor events, and other temporary needs. Tell us your event dates and location and we'll work out logistics and pricing.

Refrigerated containers can maintain the tight temperature ranges required for many pharmaceuticals and vaccines. If you have specific temperature compliance requirements, call us — we'll go over the unit's capabilities and help you determine if it meets your needs.

Yes. If your site doesn't have 460V/3-phase power available, we can provide a generator package to keep your reefer running. This is common for remote job sites, ranches, and event locations. Ask us about generator add-ons when you request a quote.

We serve all of Montana, northern Wyoming (including Sheridan), and western North Dakota (including Williston and the Bakken region). Our home base is Billings, MT.
