Quote: Just truck by itself will knock down 18-20 driving normal
No headwind and flat, its not bad with a open trailer 12-13 or so
Enclosed, headwind was horrible .. maybe 7 mpg
My half ton doesnt pull 18-20, more like 13-15
Ive had an '05, ''07, and now an '09 ALL with a HEMI and NONE got 18-20. The two 4x4's got around 13 and the new '09 two wheel drive gets around 15.4 UNHOOKED. They all pulled awesome by the way. We have a Cummins 4x4 older model. The HEMI is just as strong. The new Cummins will kill it though.
