| (a) All models can
tow trailers up to 2,000 pounds with the addition of a trailer hitch.
For towing heavier trailers up to the Maximum Trailer Weight Ratings
shown in the Trailer Towing chart, the vehicle must be equipped with
the P4 for the 3.7-liter engine or P5 for the 4.7-liter and 5.7-liter
engines for North America. |
|||
| (b) Maximum Trailer
Weight = GCWR - Curb Wt. - 150 lbs. (allowance for driver) and must be
decreased by the weight of optional equipment, trailer hitch, cargo and
passengers. Maximum trailer weights shown are rounded to the nearest 50
lbs. Tongue weight should be 10-15% of loaded trailer weight but may
not cause vehicle to exceed GVWR or GAWR. Load equalizing hitch
recommended for trailers over 2,000 pounds. |
