I'm considering either a Dodge Ram 1500 w/Hemi 5.7 and 3.55 rear-end or Nissan Titan w/ a 5.6 liter and 3.66(?) rear-end. The Dodge as configured is rated at 8500# towing and the Titan is 9100#. Both will have towing pacakges. I'll be pulling a 28' Dutchmen lite (5,400 dry weight/7,700 max wt.) that will usually be around 6,000-6,500 lbs. Most of my towing will be in South/Central GA and Florida so not many big grades. Any thoughts on the two? Any ideas on what I can figure on gas mileage for either or both?
