2008 Ford F-250 Super Duty XL 4dr SuperCab SB (5.4L 8cyl 6M)
I love this truck for it's appearance both inside and out. My wife has an 06 Acura RL and I will put the interior of this truck against the comfort of her car any day. That said, I am averaging 11 MPG and already have 23K on the trck. I'm told that this will improve once north of 25K but am not holding my breath. Simply put, the fuel economy on this truck stinks! If fuel economy is something that you are looking for in a heavy duty truck, look elsewhere.
Interior design - most comfortable truck I have ever been in. Mine is loaded with DVD, nav, etc.. Long trips pulling the travel trailer are much more comfortable and the kids don't complain near as much! Tailgate step. Overall appearance of the truck.
Fuel economy. With diesel at north of $4.00 a gallon, I am spending over $500 per month just to drive back and forth from my office. Considering buying a little Mazda or the like to use as a daily driver. Shouldn't have to consider this when I have a $50,000 truck sitting in my driveway.
