2013 Dodge Ram 2500 5.7 Hemi

I have a Dodge Hemi, and unloaded it's a rocketship compared to my F250 PSD, but loaded it's just not in the same class. Fuel mileage is a killer, I was getting 7.5 - 9 mpg towing a quite tall car hauler with around 8K in it. It would do it, but there was a lot of shifting going on (five speed manual), and foot-on-the-floor in 4th gear to maintain 55 - 60 mph if there was a headwind. There seems to be a tipping point where available power at the rpm in 4th or 5th gear seems to loose the fight against weight and wind resistance plus hills, and you really don't want to be cruising all day in third gear...

Hemi is a fantastic engine, and the truck is a total hot-rod unloaded, but at a certain point it meets it's match. 10K trailer, particularly if a tall one, is right around where it meets it's match, for me.
