After asking a lot of questions and reading the information on this forum I decided on an 07 Titan Crew, see sig. I took delivery yesterday.
A couple of things helped convince me the Titan was the right truck for me.
One, my wife just loved it and loves driving it!! I told her not too often though!

The other, was our salesman wasn't at all high pressure, and in fact went out of his way to get answers for me. He called a guy who had been a Nissan technician for 25 years, and was working for Nissan in Costa Mesa, Ca to reassure me the brake and rear differential are mostly a non issue now. He said most of the technicians he has spoken to see a declining number in those problem areas. That helped.
Plus, all the bang for the buck! I compared the Titan to the Tundra, and the Tundra Crew Cab was way more expensive, so I was looking at the Tundra Double Cab, and it was still more than the Titan. I would've had to have Toyota add several items that were already on my Titan. Of course that would've added to the price.
The difference in the ride, went to the Tundra, but just barely, and not enough to convince me to go to their side!!
So, here I am in love with my Titan and hopefully for many years to come!
