2011 Itasca Navion 24K, There aren't many motor homes that will let you brag about fuel mileage, but this one will! You can expect at least 15 miles per gallon overall from the Mercedes 3.0 liter turbo diesel engine. There's also plenty of room to move around inside and the opportunity of camping in smaller state or national park campsites. It's built by Winnebago, so you can count on durability and dependability. And it's cute!!!
