My 2014 Jeep Grand Cherokee Limited 4x4 Diesel has the "Trailer Sway Damping" as standard equipment and the Trailer Tow Group IV optional equipment, which includes Rear Load Leveling Suspension, Full Size Spare, 7 Pin Wiring Harness and Class IV Receiver Hitch. The dealer has no idea if this package also includes the electric/automatic trailer brake controller. Dealer said "check with the trailer sales guy, he'll know." There goes the confidence level in those peoplel
Anyone know the right answer?
BTW, mileage over the first 3,000 miles is 26.6mpg. Not uncommon to get 30-31 on a flat hwy at 65. Will find out soon enough what a 4,000 pound trailer does to fuel economy.
