Just bought a 2012 lt 4x4 6.0 gasser and 6 speed trans crew cab. So far I like it only 2500miles on the clock. Eats gas...... when towing, not bad on the highway with no load. 2k at 73mph. I am still trying to find the sweet spot. Trans is really smooth in auto but in manual its a bit jumpy/clanky.
