May 07, 2015I tow in the high 8,000-lbs with mine and I'm very happy with it. It's actually my 2nd 5.7L hemi truck.
My current one has 3:92 gears and the 8-speed. I use Tow Haul and essentially live in cruise control. I will manually shift down to 6th or 5th in heavy mountain terrain as required.
My last trip from South Carolina to Montreal I averaged 11.2 mpg towing the trailer. On interstates without the trailer I get in the low 20's mpg (typically 23 mpg)
