I have owned a couple of Rams, I like them fine. Currently tooling around in a '05 F350 diesel 4x4 crew cab. (6.5' bed) 5.7L powerstroke turbo diesel.
Dual axial suspension means city driving is ROUGH. Need new shocks already, the smallest bump sends my springs up into the bed lol. But... Load a couple tons in it and it purrs. No reduction in performance (thanks diesel) and the suspension gets to ride fully on the springs smoothing it out a bit
Getting ~15MPG at 2.00 a gallon right now, blend of city and highway. Too many short distance jaunts for the diesel to really optimize though.
