What Is a Class C Motorhome?
The design also means that Class C motorhomes often have a permanent bunk or additional storage above the cab. Because of these features and design, Class C Motorhomes are preferable in several ways to their older brother, the Class A Motorhome.
The idea for Class C Motorhomes was pioneered by Toyota in the early 1970s. Motivated by disappointing sales of their Hilux truck and high gas prices following the Oil Embargo of 1973, Toyota invented the Hilux Class C Motorhome.
Toyota partnered with already established RV companies like Winnebago and Chinook to permanently attach a truck camper to their Hilux pickup truck. The results were some of the first-ever Class C Motorhomes.
These micro mini motorhomes, as Toyota called them, were easier to maneuver and more fuel-efficient than the Class A Motorhomes that previously dominated the market. The Class C Motorhome and its subsequent loyal fan base were born.

Class C RV Towing Capacity
Class C Motorhomes are driveable RVs. As such, once camp is established, you will not have the convenience of a separate vehicle for quick excursions. This is why many Class C Motorhome owners will tow a car or small truck. Some even choose to tow a boat or other recreational vehicle.
While it is common to tow, Class C Motorhomes can differ greatly in their towing capacity. Additionally, the type of vehicle you plan to tow will determine whether you can flat tow or if you will need a separate trailer.
Before you tow with your Class C Motorhome be sure to check the GVWR, GCWR, and the max hitch weight of your RV.
To tow safely, you cannot exceed any of these three things. Most smaller Class C Motorhomes will be able to tow an average-sized car. Some larger Class Cs will be able to tow a truck or even larger loads.
Class C Motorhome Fuel-Efficiency
When it comes to fuel efficiency, Class C Motorhomes fall in the middle of the drivable campers. More efficient than Class A’s and less efficient than Class B’s, the average gas mileage for a Class C RV is 8-10 miles per gallon.
Many factors can determine the realized fuel efficiency of your Class C Motorhome. Speed, weight, road grade, wind, and ethanol content of the fuel you use can all impact fuel efficiency.
All of the Class C Motorhomes we reviewed are diesel. So these motorhomes will inherently get about 10% better mileage than a gas engine. This equates to a whopping 1-2 more miles per gallon.
You may be wondering what else you can do to improve the fuel efficiency of your Class C Diesel Motorhome. By taking your RV for regular maintenance checks you will avoid the decreases in fuel efficiency that comes from things like a dirty air filter.
Properly inflated tires and running your air conditioner less can both help optimize your fuel efficiency. Finally, altering your driving habits to reduce the need to accelerate and brake can also improve fuel mileage drastically.
How Much Does a Class C Diesel RV Cost in 2024?
Class C Diesel motorhomes vary in sticker price. A new diesel Class C RV will cost between $90,000 and $150,000. 2024 Super C Diesel RVs range from $180,000 to $350,000, with some ultra-luxurious models pushing $800,000.
The price can vary even more if you buy gently used. Used Diesel Class C RVs range from about $40,000 to $120,000, with Super C RVs ranging from $100,000 to $200,000.
But whether shopping for a new or used motorhome, remember to budget for the total cost of purchasing and owning one.
There are other cost considerations beyond simply the purchase price. You will want to consider sales and property tax, finance interest rate, insurance, storage costs, maintenance, dealer prep fees, tag, title, and registration fees as well as any dealer add-ons.
Once you make an investment, routine maintenance, including oil changes, tire rotation, and the like, needs to be factored into your budget. Additionally, the cost of diesel fuel and DEF can add up. Make sure you consider and plan for maintenance as you would any other vehicle you own.
