Went on our first trip with our new Ram 2500 (posted about it in a previous thread).
Truck towed GREAT. Loved all the new features, seat warmer, steering wheel warmer, exhaust brake, Sirius radio and traffic/travel apps, more HP and torque. Truck definitely towed with more "authority" than my old 07 2500 (5.9 CTD).
For the most part, hit the Tow/Haul button, put it in drive and went. It down shifted a few times going up hills...once or twice I dropped it out of OD (6th) when it seemed to be lagging a bit going up a hill. There was a few times where it was in 5th and stayed there for awhile before it went back into OD.
Other than the higher RPM/bit more engine noise there did not seem to be much difference in 5th and OD.
Anyone else work things differently?
