 I ordered this vehicle with all the bells and whistles. The 7.3L Powerstroke diesel is everything I expected. Fuel mileage ranges from 15.5 mpg in the dead of the winter to 18.5 - 20.0 mpg in the summer months. The engine supplies plenty of power and the transmission performs flawlessly. It handles well and has a good ride despite the 1 ton rating. Maintenance cost is typical and I encountered nothing unusual in repairs.  This van weighs in around 7950#, so it is no lightweight.  In fact, since everything is heavy duty, it tends to go further before replacement is needed.
