Maximum Loaded Trailer Weight; GCW (Gross Combination Weight); GCWR (Gross Combination Weight Rating)- Page 684

GCW (Gross Combination Weight)

 is the weight of the loaded vehicle (GVW) plus the

weight of the fully loaded trailer.
 

GCWR (Gross Combination Weight Rating)

 is the maximum allowable weight of the

vehicle and the loaded trailer - including all cargo and passengers - that the vehicle can
handle without risking damage. (Important: The towing vehicle's braking system is rated for
operation at GVWR, not at GCWR. Separate functional brakes should be used for safe
control of towed vehicles and for trailers weighing more than 1,500 lbs). 

The GCW must

never exceed the GCWR.

Maximum Loaded Trailer Weight

 is the highest possible weight of a fully loaded trailer

the vehicle can tow. It assumes a vehicle with only mandatory options, no cargo (internal or
external), a tongue load of 10

－

15% (conventional trailer) or king pin weight of 15

－

25%

(fifth-wheel trailer), and driver only (150 lbs). 

Consult your dealership (or the RV and

Trailer Towing Guide provided by your dealership) for more detailed information.
Tongue Load or Fifth-Wheel King Pin Weight

 refers to the amount of the weight that a

trailer pushes down on a trailer hitch.
 

Examples:

 For a 5000 lb conventional trailer, multiply 5000 by 0.10 and 0.15 to obtain a

proper tongue load range of 500 to 750 lbs. For an 11,500 lb fifth-wheel trailer, multiply by
0.15 and 0.25 to obtain a proper king pin load range of 1,725 to 2,875 lbs.

WARNING

Never Exceed GVWR or GAWR Specifications:

Exceeding the GVWR or the GAWR specified on the certification label is dangerous. Exceeding
any vehicle rating limitation could result in a serious accident, injury, or damage to the
vehicle.
Do not use replacement tires with lower load carrying capacities than the originals because
they may lower the vehicle's GVWR and GAWR limitations. Replacement tires with a higher
limit than the originals do not increase the GVWR and GAWR limitations.
Never exceed the GVWR or the GAWR specified on the certification label.
