love my 2011. Before that had only GM (4 of them traded every 18 months). Had major issues with a 2010 Silverado 6.2 and traded on the titan. 100,000 miles and no issues. Gonna wait for the new model and get it.
FYI Nissan has confirmed all new titan for 2015 with 5.0L cummins engine as an option. Rumour has it around 300hp and 460 touque. I do however have my doubts about the cummins motor as Dodge must have some kind of exclusivity agreement.
