If I had to do it over again I'd still go with my Dodge Ram 3500, with the 6,7L cummins and the 6 speed tranny it hauls my 15.000lbs plus fiver up and down the road with ease and I love cruising up the Smokey's with out feel I'm in too little of a tow vehicle and on the way down the exhaust brake is the only way to go, four door for guests n' grandkids, 8' box to carry what I need and add tracking stability add the Retrax locking tonneau and the stock locking tailgate to secure my gear and last but not least the dually rear end which believe me DOES make a difference. When you go shopping for the truck remember your dealing with sales people who probably don't know jack about hauling a fiver, get your opinions from actual fiver owners who are doing SERIOS hauling not weekends.
But the big reason I love my truck so much is it just looks sooo damn good!!!
