A stripped chassis is a foundation. The floor plan has to work before the order does.

Know why the cab is missing

A cutaway preserves Ford's cab. A stripped chassis does not, which lets the second-stage manufacturer design the driver area into the body. That can be the right foundation for a walk-in delivery vehicle, a motorhome, or a specialized mobile workspace. It also means visibility, doors, seating, restraints, mirrors, HVAC packaging, controls, and body structure depend heavily on the builder.

Start with a floor plan that includes the driver, not a rectangle behind the front axle. Mark the step-in, seat position, sightlines, turning needs, aisle, shelves, tanks, batteries, lift, generator, cargo zones, and service access. The person who drives a Southern Oregon route for eight hours will notice a poor step or blocked mirror long after everyone has forgotten which chassis arrived first.

Choose E-350 or E-450 with an axle worksheet

Ford's 2027 guide lists dual-rear-wheel E-350 Stripped Chassis configurations with 138-, 158-, and 176-inch wheelbases and E-450 configurations with 158- and 176-inch wheelbases. Published maximum GVWR rises from 11,500 pounds on a listed E-350 configuration to 14,500 pounds on E-450. Maximum payload runs as high as 9,640 pounds in the listed E-450 data.

The biggest number is not automatically the right order. A longer wheelbase changes maneuverability and the way the body spans the frame. A heavy rear lift, water tank, or cargo zone can consume rear-axle capacity while unused total payload remains on paper. Ask the builder for estimated front and rear weights in running condition and at the heaviest legal load.

• Show the curb, driveway, dock, campground, or alley where the finished vehicle must turn
• Place fixed tanks, batteries, lifts, and generators before calculating cargo capacity
• Check front and rear axle estimates at empty, normal, and maximum load
• Reserve safe access for maintenance, towing, jump points, and tire service

Put the builder, dealer, and operator on one schedule

Ford lists a 7.3-liter gas V8 at 325 horsepower and 450 pound-feet for 2027 E-Series. The fleet guide also identifies motorhome, school, shuttle, gaseous-engine, electrical-connector, and other available preparation packages on select models. The chosen body and use decide which provisions are relevant. Ordering a chassis without them can create expensive work later or make the intended build unsuitable.

Write down who orders the chassis, who transports it, who completes and certifies the vehicle, who handles inspections and registration, and where warranty responsibility changes. Include realistic production slots rather than one promised delivery date. Butler Ford should see the same body specification and weight worksheet as the upfitter; that is how a chassis order becomes part of a finished plan.
