Had mine for 17 months. Great truck as the tile says. Fuel mileage isn't great but with the engine this thing has I am not surprised. This thing with a trailer will walk off from any Ford I have owned or driven and I have had nothing but Fords for the last 30 years until now. Drove a new 2009 F150 and it still doesn't compare. I have had no issues whatsoever and am very happy with the truck.
Engine power, towing ability, spacious cab.
Keep building it. Nissan has recently decided to let Chrysler build their trucks starting in 2010. So if you want a good Nissan Titan, get one now. Otherwise you will end up with a rebadged Dodge "shudder shudder"
