One catalog configuration per trim. Each trim comes in several engine, axle, cab and bed combinations with different ratings; a truck's own window sticker has its exact ones. A dash means the figure isn’t in our catalog or isn’t confirmed against an OEM source.
Factory tow packages
Verified packages with an OEM order code and what they change for towing. A rating is shown only where every verified source for that code agrees.
