2006 titan
 2006 titan 4wd/LE. have truck for 1 month and 1000  miles.  Love performance.  Gas mileage on first tank was 13.5mpg mostly city.  16.5 on hwy at 75 mph with only 700 miles on engine.  Will use the bed extender on next trip and  see gas milage with tailgate down. So far, the EPA estimate is fairly accurate.  I'll see what the truck gets when I get the engine broken in and some miles on it.  If one has ideas for increased mpg. Let me know.  Did alot of research and I think the Titan is the best truck on market.  Will reevaluate at 10,000 miles.
