I have a 2011 Titan and I love it. People are afraid of the unknown and I think that's a big reason sales are down.
The price I paid was incredibly low, right in line with the big 3 at the best sale pricing. My Titan pulls anything I hook up to it and I also use it for offroading fun. No major issues in its first three years with me and loaded with features that you only get on the premium models of the big 3.
I'm waiting to see the diesel model too, wondering how much different it will look and what the rest of the powertrain looks like.
2010 Jayco Eagle 351RLSA
2011 Nissan Titan 4x4 (don't worry, I don't pull the Eagle with it!)
Currently shopping for a Silverado 3500 Duramax
Oh, and I have a tent... Somewhere around here....
