Mobile Mini alternatives for container rental in the Mountain West

Mobile Mini is no longer a separate operating brand. It merged with WillScot in 2020, and WillScot combined its brands under the WillScot name in 2024. WillScot lists storage containers among a larger office and modular range and routes rental pricing through a quote request (willscot.com, investor release on combining the Mobile Mini brand under WillScot, checked September 11, 2026). For that reason, the current baseline below reads WillScot.

A Mobile Mini alternatives search often begins with a simpler need than a modular-building search: one secure box, a known site duration and a delivery date. This guide therefore starts with JOLT's 10, 12, 20 and 40 ft storage choices, short Colorado minimums and published delivery bands before widening to storage specialists.

What does JOLT rent for storage?

JOLT rents four lengths of one-trip ISO storage container. The 10 ft storage container is the shortest choice for a constrained pad. The 12 ft option adds room without taking a 20 ft footprint. Both have cargo doors, a side man door and one barred window.

The 20 ft storage container is a standard-height box with end cargo doors, four lock bars and a welded lockbox. It has no man door or window. The 40 ft storage container is a high-cube unit with cargo doors and a welded lockbox. It doubles the nominal length but also needs the longer placement route.

Storage container rent

Item	Price
20 ft storage container Fits most driveways.	$295 /mo
Most popular 40 ft storage container One trip. Three months. Everything on site. 3-month minimum	$425 /mo
12 ft storage container Walk-in door. Fits a driveway.	$325 /mo
10 ft storage container Fits where a 20 ft will not.	$225 /mo

The 10, 12 and 20 ft storage units have a 1-month minimum in Colorado. The 40 ft box has a 3-month minimum. After the minimum, rent continues month to month. Pickup requires at least 15 days' written notice, and rent runs until JOLT retrieves the empty, clean and accessible unit.

That structure can fit a crew needing one box for two months: choose a smaller storage length, reserve for the expected period and send pickup notice early enough for retrieval planning. Do not treat the notice as an automatic end date. The unit remains rented until it is picked up.

How do delivery zones change the choice?

JOLT dispatches from Gypsum, Colorado, so transportation depends on the destination rather than a flat statewide assumption. Zones A–E publish a fee in each direction, and pickup equals delivery. Zone F publishes delivery but requires a pickup quote in writing before dispatch. Every Zone F unit has a 12-month minimum.

For a short Colorado storage job, compare the rent period plus both truck movements and recurring charges. A low monthly line can be misleading when a distant box moves twice. For a Wyoming, Idaho, Utah or Montana job lasting only two months, JOLT is not a fit because Zone F requires 12 months; use the table of operators to identify a company with a yard nearer the site and confirm its term.

The delivery-zone page identifies the covered bands. Placement remains subject to access. The customer provides a firm, level, well-drained pad and a clear truck route. Plan roughly 70 ft of straight-line clearance for a 20 ft box and roughly 100 ft for a 40 ft box, then account for gates, bends and overhead hazards.

Which storage specialists belong on the call list?

Dry Box operates from Denver and Salt Lake City, lists storage containers and container offices, and prints starting rental rates. Its Salt Lake City page says next-day delivery is often available around that market (dryboxusa.com, Salt Lake City page, checked September 11, 2026). It is a useful comparison when either yard is closer than Gypsum.

Mobile Modular Portable Storage has branches in Longmont, Salt Lake City and Boise. It lists storage, office, office-and-storage combo and refrigerated containers, uses 30-day renewable rental periods, and says units deliver within days rather than weeks (mobilemodularcontainers.com, products page, checked September 11, 2026). It belongs on a list that may expand from storage into a combo.

MoCan Containers is the Montana storage-focused entry, with yards in Billings and Gallatin Gateway near Bozeman. It lists 20 ft and 40 ft boxes, terms from one month through longer arrangements, and delivery including long distances (mocanmt.com, rentals page, checked September 11, 2026). Its site prints starting rental rates.

Cascade Container operates from a Salt Lake City depot and lists dry, refrigerated and office containers. Its rental page states a one-month minimum followed by month-to-month use, while rentals go through a quote form (cascadecontainer.com, container rentals page, checked September 11, 2026). Consider it when refrigeration or a Utah depot matters.

Haulaway Storage Containers lists 10, 20, 26 and 40 ft storage boxes from Castle Rock. Its site describes short- or long-term rentals without naming a fixed minimum and says delivery usually occurs within one business day (haulaway.com, facts page, checked September 11, 2026). Confirm both term and availability in its written quote.

Warehouse on Wheels trades in Colorado as Colorado Trailer Rentals, with drop lots in Denver and Colorado Springs. It lists storage trailers, ground-level containers and 20 ft and 40 ft office-and-storage combos, describes 30-day rentals and says on-site timing is 24 to 48 hours (warehouseonwheels.com, Colorado Trailer Rentals brand page, checked September 11, 2026).

Storm's Specialty Services has a Grand Junction yard and lists storage containers and mobile office trailers. Its site says the quoted cost includes delivery and placement (storms-specialty.com, FAQ page, checked September 11, 2026). That quote format needs careful handling: identify whether pickup and every recurring item are also included.

Montana Mobile Storage lists 10, 20 and 40 ft storage boxes and a 20 ft office container from Missoula. Its rental and contact pages route the customer to a form, while minimum and delivery statements should be confirmed in the written quote (montanamobilestorage.com, rental page, checked September 11, 2026).

These companies are not interchangeable. A storage trailer differs from a ground-level ISO box, a refrigerated unit answers a different requirement, and a combo unit gives up storage area for office use. Put the exact equipment description beside every quote.

How does the wider alternatives table help?

The table uses WillScot as the baseline because that company now carries the Mobile Mini lineage. The rows after it include JOLT and every other ranked operator in directory order. The order rewards visible rates, stated terms and delivery information, yard reach and office products; it does not compare quoted amounts.

Use the table to narrow by yard state and listed product, then contact only operators that plausibly serve the job. A named yard does not prove that the required length is available, and a delivery statement does not guarantee your requested day. Ask for inventory and timing together.

For a direct historical-brand comparison, see JOLT versus Mobile Mini. For office trailers and modular choices, the WillScot alternatives page takes a broader office-first view.

What belongs in a one-box written comparison?

First define the box. Record length, height, door arrangement, lockbox, office partition if any and expected condition. Confirm that your stored materials are suitable and that the proposed location provides drainage and routine access without blocking construction traffic.

Next define the clock. Ask for the minimum rental period, billing increments after that period, pickup-notice deadline and the event that stops rent. JOLT's smaller Colorado storage boxes use a 1-month minimum, but rent continues until retrieval. Another operator's "30-day" wording may still carry separate notice or pickup scheduling requirements.

Then collect every charge category without asking a competitor to match somebody else's structure. Request delivery, pickup, recurring fees, deposit or waiver options, taxes, relocation, cleaning or damage standards and annual changes. If a site page provides no verified statement, mark the field "Confirm in the written quote" and leave it open until the operator answers.

Finally, make the delivery week and site duties explicit. Photograph the route, measure straight clearance, check gate width and overhead lines, and identify snow, mud or soft shoulders. The dispatcher should review unusual access before the delivery truck is committed.

How do you reserve JOLT storage?

Review all published figures on pricing, then use reserve with the job ZIP and selected size. The flow shows the delivery week before payment. The reservation deposit is applied to the first invoice.

Written cancellation received more than 14 days before the first day of the delivery window is free. Cancellation inside 14 days forfeits the deposit. If the job is uncertain, put the decision date on the project calendar rather than relying on a verbal schedule change.

Once delivered, keep the container accessible and send at least 15 days' written pickup notice after the minimum. If the unit must move elsewhere on the same site, request an on-site relocation rather than moving it with job equipment. The published process keeps dispatch, billing and responsibility tied to a written record.
