I am looking for a good tow vehicle for a 9000# trailer with hitch not 5th wheel. Planning some cross country trips and with a budget of 35K to 40K and liking the Laramie trim is there one year better than another for reliability, serviceability mileage etc? I'm new to Dodge and diesel, with my prior experience being with a under powered gas hungry SUV, I would like good power and towing experiences as trouble free as possible. Been using a 9000# rated SUV but it doesn't have the torque for these West Coast long grades, and forget it trying to clime thru the mountains. Help is appreciated.
