 I owned a 04 Titan SE Crew cab 4X4 for 10 years. I bought it used and put 246000 miles on it with no mechanical issues. I loved that truck and thought it to be very comfortable and reliable. I purchased the 17 PRO4X with every available option and so far I can report that I do love this truck. As others have stated, it is bigger than the older one and requires more turning radius. However, other than that I have had no issues. This one has all the gadgets and electronic gizmos that my 04 did not making it very fun to drive. My only complaint might be the lack of usable space under the rear seats. The new Titan has lockable storage boxes under the rear seats and although a nice idea, they are not really big enough for anything such as tools. I used to carry a toolbox under the seat of my old one. Also, being a four wheel drive I believe the PRO4X should come equipped with better off road tires than the other Titans available. My first time off road against my brothers Tundra was not an impressive outing. The locking Diffs are nice however, more meaty off road tires are needed. Other than that, really great truck. I'm sure i'll be driving this one for many years.
