Maximum trailer weight for all cutaway (E-350 and E-450) vehicles
must be calculated by subtracting the weight of the vehicle (including
incomplete vehicle weight and payload which includes second unit
body weight, cargo and passengers) from the GCW. Otherwise,
maximum trailer weight is 4536 kg (10000 lbs)
For high altitude operation reduce GCWR by 2% per 300 meters (1000
ft) elevation.
To determine the maximum trailer weight designed for your particular
vehicle as equipped, follow the section Calculating the load your
vehicle can tow/carry earlier in this chapter.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Distribute the load so that only 10 to 15% of the total is on the tongue.
Tie down the load so that it does not shift and change the weight on the
hitch.
Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components carefully after any towing operation.
Note: Do not exceed the GVWR or the GAWR specified on the
certification label.
Towing trailers beyond the maximum recommended gross trailer
weight exceeds the limit of the vehicle and could result in
engine damage, transmission damage, structural damage, loss of vehicle
control, vehicle rollover and personal injury.
Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. See your dealer or a reliable trailer
dealer if you require assistance.
Hitches
Do not use or install hitches that clamp onto the bumper or to the axle.
Underbody hitches are acceptable if installed properly.
