Bought my 06' Titan in June 06'. Have had it back to the dealer 6 times for small problems (windows, door handle problems for example). Problems seem to be fixed and love the truck otherwise. Great power, fun to drive and handles my 23 ft. camper so much better than my last Ford truck did. That five speed transmission is fantastic pulling a heavy load. My Ford couldn't do the highway speed limit and sounded like it would blow when it would downshift going up the smallest incline. The Titan's five speed tranny handles the speed and inclines wonderfully and I couldn't be happier. Well, maybe with a few more miles per gallon. E85 fuel economy is brutal in this vehicle.

Not the best looking truck on the market. Front end needs to be overhauled. Someone said it best in a review before mine when they said it could use a wheel flares and the orange lights on the dash get a little tough at night.
