I am curious to know what "ma Snart" gets for mileage with that. With my 2010 1500 and the v-nose 20' I average 10.5. That is with the 3.92s and air bag helpers on the back.
My Hemi had 3.92 gears and the mileage depends on vehicle speed and wind. On average I get around 9 to 10 with the car trailer. Not much different than my snowmobile trailer with the v nose. Most of the time I do not have a trailer behind it and average around 15 (would be better but I have a hard time keeping my foot out of it - LOL!).
I love the Hemi engine. And no stinking diesel to have to pump.
