WARNING: When loadingthe roof racks, we recommendyou evenly distribute the load,as well as maintain a low centerof gravity. Loaded vehicles, withhigher centers of gravity, mayhandle differently than unloadedvehicles. Take extra precautions,such as slower speeds andincreased stopping distance,when driving a heavily loadedvehicle.
The gross combined weight mustnever exceed the Gross CombinedWeight Rating.
USING A SLIDE-IN CAMPER
For information regarding the use ofslide-in campers, consult the TruckCamper Loading document supplied withyour vehicle.
LOCATING THE SAFETY
COMPLIANCE CERTIFICATION
LABELS
Safety Compliance Certification LabelExample:
The Safety Compliance Certification labelis located on the door hinge pillar,door-latch post, or the door edge thatmeets the door-latch post, next to thedriver seating position.
WHAT IS THE GROSS AXLE
WEIGHT RATING
GAWR (Gross Axle WeightRating)
GAWR is the maximum allowableweight that a single axle (front orrear) can carry. These numbersare on the Safety ComplianceCertification label.
WHAT IS THE GROSS VEHICLE
WEIGHT RATING
GVWR is the maximum allowableweight of the fully loaded vehicle.This includes all options,equipment, passengers and cargo.It appears on the SafetyCompliance Certification label.
WHAT IS THE GROSS
COMBINED WEIGHT RATING
Gross Combined Weight Rating(GCWR) is the maximumallowable weight of the vehicleand the loaded trailer, includingall cargo and passengers, that thevehicle can handle without riskingdamage. (Important: The towingvehicle’s braking system is ratedfor operation at Gross Vehicle
Weight Rating, not at GrossCombined Weight Rating.)

Separate functional brakes shouldbe used for safe control of towedvehicles and for trailers where theGross Combined Weight of thetowing vehicle plus the trailerexceed the Gross Vehicle WeightRating of the towing vehicle. SeeRecommended TowingWeights (page 368).
CALCULATING PAYLOAD
Tire and Loading Label InformationExample:
Payload is the combined weightof cargo and passengers that yourvehicle is carrying. The maximumpayload for your vehicle appearson the Tire and Loading label. Thelabel is either on the B-pillar or theedge of the driver door. Vehiclesexported outside the US andCanada may not have a tire andloading label. Look for “Thecombined weight of occupantsand cargo should never exceedXXX kg or XXX lb” for maximumpayload. The payload listed on theTire and Loading Information labelis the maximum payload for yourvehicle as built by the assemblyplant. If you install any additionalequipment on your vehicle, youmust determine the new payload.Subtract the weight of theequipment from the payload listedon the Tire and Loading label.When towing, trailer tongueweight or king pin weight is alsopart of payload.
CALCULATING THE LOAD
LIMIT
Steps for determining the correctload limit:
1.Locate the statement "Thecombined weight of occupantsand cargo should never exceedXXX kg or XXX lb." on yourvehicle’s placard.
2.Determine the combinedweight of the driver and
passengers that will be ridingin your vehicle.
353
2023 Super Duty (TFH) Canada/United States of America, enUSA, Edition date: 202211, DOMLoad CarryingE198719

3.Subtract the combined weightof the driver and passengersfrom XXX kg or XXX lb.
4.The resulting figure equals theavailable amount of cargo andluggage load capacity. Forexample, if the “XXX” amountequals 1,400 lb. and there willbe five 150 lb. passengers inyour vehicle, the amount ofavailable cargo and luggageload capacity is 650 lb.(1400-750 (5 x 150) = 650 lb.)
5.Determine the combinedweight of luggage and cargobeing loaded on the vehicle.That weight may not safelyexceed the available cargo andluggage load capacitycalculated in Step 4.
6.If your vehicle will be towing atrailer, load from your trailerwill be transferred to yourvehicle. Consult this manual todetermine how this reduces theavailable cargo and luggageload capacity of your vehicle.
Helpful examples forcalculating the availableamount of cargo and luggageload capacity
Suppose your vehicle has a1400-pound (635-kilogram) cargoand luggage capacity. You decideto go golfing. Is there enough loadcapacity to carry you, four of yourfriends and all the golf bags? Youand four friends average 220pounds (99 kilograms) each andthe golf bags weigh approximately
30 pounds (13.5 kilograms) each.The calculation would be: 1400 -(5 x 220) - (5 x 30) = 1400 - 1100- 150 = 150 pounds. Yes, you haveenough load capacity in yourvehicle to transport four friendsand your golf bags. In metric units,the calculation would be: 635kilograms - (5 x 99 kilograms) -(5 x 13.5 kilograms) = 635 - 495 -67.5 = 72.5 kilograms.
Suppose your vehicle has a1400-pound (635-kilogram) cargoand luggage capacity. You andone of your friends decide to pickup cement from the local homeimprovement store to finish thatpatio you have been planning forthe past two years. Measuring theinside of the vehicle with the rearseat folded down, you have roomfor twelve 100-pound(45-kilogram) bags of cement. Doyou have enough load capacity totransport the cement to yourhome? If you and your friend eachweigh 220 pounds (99 kilograms),the calculation would be: 1400 -(2 x 220) - (12 x 100) = 1400 - 440- 1200 = - 240 pounds. No, you donot have enough cargo capacityto carry that much weight. Inmetric units, the calculation wouldbe: 635 kilograms - (2 x 99kilograms) - (12 x 45 kilograms) =635 - 198 - 540 = -103 kilograms.You will need to reduce the loadweight by at least 240 pounds(104 kilograms). If you removethree 100-pound (45-kilogram)
cement bags, then the loadcalculation would be: 1400 - (2 x

220) - (9 x 100) = 1400 - 440 -900 = 60 pounds. Now you havethe load capacity to transport thecement and your friend home. Inmetric units, the calculation wouldbe: 635 kilograms - (2 x 99kilograms) - (9 x 45 kilograms) =635 - 198 - 405 = 32 kilograms.
The above calculations alsoassume that the loads arepositioned in your vehicle in amanner that does not overloadthe front or the rear gross axleweight rating specified for yourvehicle on the Safety ComplianceCertification label.
