OK have put 1200 miles on my new Titan HD. I am a little disappointed in the millage at 18.1 combines city and highway. The ride has been good and power is good throughout the power range. The shifting smoothness has improved with some miles on the vehicle. I drove a GMC 2500 before buying a this truck with a price range of 62K to 67K and find this vehicle has the same ride and power of the GMC at 46K. Overall at this point I like the New HD and would recommend it to others. Will tow my 9000 lb RV in a few weeks and will update the results.
