Step van vs. cargo van vs. box truck

All three can carry a business. They're built for different days, and the difference shows every time someone climbs in, works inside or makes a stop. Here's how to choose.

The short answer

Choose a step van when people work inside the vehicle or make many stops a day. Choose a cargo van when the job is light and the vehicle has to drive and park like a car. Choose a box truck when the goal is the most cargo per trip, with fewer stops. [1][2]

Why mobile businesses use step vans

A step van's walk-in body lets the crew move between the cab and the work area without getting out, and its open, square cargo area is easy to lay out as a kitchen, bar, storefront or workspace. Bodies are built with standing height inside: Utilimaster lists 81 or 85 in.

Walk-in bodies are typically aluminum. Morgan Olson's are all-aluminum, which it says adds years of service compared with cargo vans built from materials that rust sooner. [2][3]

When a cargo van is enough

If one person works out of the vehicle, the equipment is light, and the job is city streets and tight parking, a cargo van can be the better buy. The trade-off is room: cargo vans typically have less interior space, and the crew works around shelving or stacked goods. [2]

When a box truck makes more sense

Box trucks have the advantage in raw cargo capacity, so they suit bulk loads and routes with fewer stops. The cost is access: the driver usually has to get out of the cab, walk to the rear and open a roll-up door at every stop, which adds up on a route. [1]

Questions to settle first

Before you pick a platform, answer these:

  • How many people work inside, and for how long?
  • How many stops a day, and how often does someone get in and out?
  • What's the loaded weight with equipment, water and stock?
  • Where will it park: streets, events, docks or job sites?
  • Will you build one vehicle, or a fleet on one spec?

Common questions

Does a step van carry less than a box truck?

Usually, in raw volume. Box trucks are built for the most cargo per trip; step vans trade some of that for walk-through access and faster stops.

Can I stand up inside a step van?

Yes. Walk-in bodies are built with standing height; Utilimaster lists 81 or 85 in inside.

Why are so many food trucks step vans?

The walk-in body gives standing room, flat walls for equipment and a walk-through from the driver's seat, which makes a kitchen layout simpler than in a cargo van or a box with no cab access.
