FORD 2003 F-550 v.2 - Manual (Page 146)

2nd unit bodies are not included in maximum trailer weight ratings. The
weight of the additional “body” must be subtracted from the maximum
trailer weight.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components carefully prior to and after any towing operation. The
following trailer towing charts apply to vehicles equipped with gasoline
engines; for Diesel engines, refer to the 6.0 Liter Power Stroke Direct
Injection Turbo Diesel Supplement.
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.
Refer to Transmission temperature gauge in the Instrument cluster
chapter for transmission fluid temperature information.
