2010 Itasca Navion 24J MERCEDES DIESEL WITH ONLY 36,000 MILES Efficiency at its Finest. A powerful and efficient Mercedes-Benz 3.0 liter V6 turbo-diesel engine is the hallmark of the Dodge Sprinter chassis on which the Navion is built. Adaptive ESP technology senses vehicle load and performance parameters to maximize handling, control, and driving stability. An exceptionally smooth ride is due to the independent front suspension system with a transverse mono-leaf spring and stabilizer. Tip-shift technology allows manual shifting of the five-speed automatic electronic transmission if the desire arises. And SmartSpace design, with features such as the comfort sofa / sleeper, makes the Navion as much fun at the campsite as it is on the road.
