Good write up, thanks for posting it. It's good to get some real world feedback on pricing and how it works towing/driving. I paid $39k for my Ram which sounds like it's at a similar trim level, although mine does also have 4wd (sticker was $51k). Even accounting for 4wd it looks like there is a bit of a real world discount on the Titan compared to a more traditional HD model, which there should be. Figure around $35k for a 4wd version and you've got a pretty compelling truck compared to a similarly priced half ton.
Nissan makes some really good vehicles. My family has had a lot of luck with them over the years, going all the way back to the old hardbody pickups in the early to mid 1980s.
