I drove a 99 24Valve for 13 years and really liked it. Well I got the itch and bought a 2011 in 2012. The milage was 15 to and from work, 18 at best on the highway. I deleted the truck in 2016 and couldn't be happier. The truck has way more power and milage now. I took a road trip Friday to pick up a 69 Chrysler 300. The drive down with my 2500 lb trailer in tow turned in 19 mpg, running 70-75. On the way back with the car loaded, we got 18 mpg. This was an almost 900 mile round trip. My truck is a Bighorn, 4X4, crew cab.
