I have over 2000 miles on the new truck now.....Made a 650 mile run today to drop the kids off with the grandparents for spring break.....The first 325 miles were north with a 30 mph tail wind and i averaged 19.2mpg!!....then on the way back into the same wind i got only 14.4mpg..This was with the cruise set at 75mph...It was a nice smooth ride even into the wind and everything worked great....Only vibration i felt was the bass from the audiofile sub under the back seat.....One thing i really dont like is the heated seats go off after a few minuts by themselves.....wish they were on a toggle switch like the wifes Jeep....but thats a very minor thing and its no problem to just push the button again.....Love this truck!!
