Our Vans

The van that quickly became a legend — the 4x4 Ford E-350 Classic.

We start with a Ford E-350 cutaway chassis with the 7.3L V-8 Godzilla motor. We then tear down the stock suspension and install a custom designed Dynatrac Pro Rock 60 front axle in the front to pair with the rear Ford full float Dana 60 axle.

Heavy Duty drivelines connect the axles to an Atlas II transfer case. Partial military wrap leaf springs, Sumo Springs in the rear and purpose-built Fox shocks round out our suspension package which results in a 6” lift over factory and can accommodate 35” Tires.

We then mate our custom designed fiberglass body to the Ford chassis. The fiberglass body with steel cage interior is a touch wider on the exterior than the old Econoline vans but provides over 6 feet of interior width for extra storage and bed space. Our pop top with dual electric motors is then attached to the body to allow for full stand up height and extra sleeping area with a bed big enough for 2 adults.

Are you looking for the ultimate adventure vehicle? Our Field Van Classic 4x4 will take you to the limits and beyond. Often hailed as the most capable RV in the world, we stand behind its reputation and are proud to be the exclusive provider of this one of a kind vehicle. Get the hell in!

Conversion Overview

There are really three major points in building out a van.

The first is deciding which manufacture chassis to use. The next is designing the layout.
The final step is selecting the options to be installed.


Field Van offers a variety of uniquely designed, and well thought out floor plans. You can start with one of our premier plans that have been perfected over decades of van building, or work with one of our experienced project managers to create something custom.
