The Ram is a 2003. I am either towing a 16ft landscape trailer with 2 ztrs and a walk behind or my dump trailer loaded with mulch, stone, brush etc. The trucks seems to get a stead 10mpg towing no matter what. Driving around town without a trailer Is when im getting 11-12. This truck pretty much does zero highway driving.... its unfortunate because I have seen it just to as much as 21MPG crusing on the highway.
