Gotcha...that gives me a good guess at mileage if I decide to trailer the Jeep rather than flat tow. I would guess a single vehicle flatbed (tandem axle) would weigh somewhere around 1500 lbs. (give or take). That would put my overall towing somewhere under the 6k lb. mark..

 

Look here is the deal with all third gen Dodge trucks.....The factory bumper is a class 3 bumper good for 5000 lbs. You can tow from that, but would recomend going to your local U-Haul dealer and have them put the receiver (that bolts to that tubular bar under the bumper) on the truck. It will give you more towing options. If your truck came with the Hemi it should already have a tranny cooler. The receiver hitch is not a big unit like traditional units, because the big part of the traditional units is already there, hence that big tubular bar. Dodge already put it on there. Thats what puts Dodge on top.
