I was towing with a 2004 Jeep GC with the 235 horse/ 295 ft lbs 4.7. I had a chance to move up to the Dodge truck as a more stable towing platform. I didn't NEED the hemi so I opted for the 310 horse / 330 ft lbs 4.7 ( big difference). I did get the 3.92 anti-spin rear and the full towing package. It is rated to tow 7300 lbs. I got 15 mpg around town and as of yet haven't had a chance to drive it solo on the highway. I got 10-11 while towing my 28 ft trailer. I should be able to knock off 20 mpg on the highway as it is taching 1800 rpm @ 60 mph. I towed in 4th gear pulling 2500 rpm at 61 mph.
Much more powerful 4.7 , good turning radius. Very QUIET ride , soft ride with the coil springs, large center console, 2 glove boxes , exterior looks sharp.
Owners manual seems sparse with info. There was nothing about the tow haul mode or how it works.
