What Is a Class C Diesel RV?
A Class C diesel RV is one of three classes of motorhomes. Class C RVs fall between a class A and B motorhome in chassis size and floorplan size. While you can get Class Cs in diesel and gas engines, diesel tends to offer the best fuel economy and longevity. Diesel engines are beneficial and powerful for riding through mountains and towing vehicles.
What Is the Most Reliable Diesel Motorhome?
Any diesel engine in a motorhome will provide a level of reliability you may not get in a gas engine. The Mercedes-Benz chassis tends to be the most popular and heavy-duty for Class C RVs.
The 3.0L 6-cylinder Turbo-diesel engine with seven-speed automatic tip shift speed transmission 188 HP/325 lb Torque gets some of the best reviews. For example, you’ll find this engine in the Winnebago Vita and Tiffin Wayfarer, which we’ll discuss in more detail coming up.
For larger RV’s the Cummins 6.7 has become a well-respected power plant that has been powering RAM 3500 trucks reliably for years.
