What Are the Best Super C RVs?

When introducing the main types of motorhomes, we typically stick to the common Class A, B, and C categories. But there are two important motorhome types that some might call ‘tweeners’: the Class B+ and the Super C RV. 

While Class B+ RVs are designed to provide more luxury than your standard class B camper van, the best super C RVs tackle more rugged, off-road use than a standard Class C motorhome. Let’s learn more about Super C RVs and explore some of the top-selling models you can find at Camping World dealerships nationwide.

What is a Super C RV?

A Super C RV is essentially a heavier-duty upgrade to a standard Class C motorhome. Most Super C motorhomes are built on a larger, heavier truck chassis, such as the RAM® 5500 SLT, the Freightliner® S2RV, and the Ford® F-550 Chassis.

Many Super C RVs also boast more powerful diesel engines, allowing them to tow heavier loads than an average Class C motorhome. But the significant identifying feature shared by Class C and Super C RVs is the cabover bunk area above the driver’s cockpit, commonly used for storage, sleeping, or as a loft hangout area.

What are the Pros and Cons of Super C RVs?

Here are some of the most important advantages and disadvantages of Super C RVs, as compared to other motorhomes:


  • Towing Capacity. Larger diesel engines and beefed-up towing packages allow you to tow heavier loads.
  • Interior Living Space. A larger, heavy-duty chassis allows for bigger builds with more spacious floorplans.
  • Holding Tank Capacities. Larger fresh, gray, and black water holding tanks allow you to camp longer between dump station visits.
  • Extended Wheelbase. A wider wheelbase provides more stability and security when navigating this RV through various road conditions.
  • Exterior Storage. Massive basement compartments provide ample room for grills, camping chairs, pop-up shelters, and more.
  • Suspension. Upgraded suspension for a smoother, more comfortable ride and an improved ability to handle unmaintained roads. Learn more about RV suspension.
  • Engine Maintenance. The engine is located under the hood in the front, providing easier access for mechanics than what’s required in Class A diesel motorhomes.


  • Maneuverability. Larger RVs require more care and precision from the open highway to entering gas stations and parking lots. Still, most Super C RVs fall under the 26,000-pound limit, meaning you don’t need a special license to drive them.
  • Fuel Efficiency. On average, this RV type gets less than 10 miles per gallon. This is closer to what you’ll get with most Class A diesel RVs but less than you’d get with a compact Class B RV.
  • Price Point: Super C RVs start at a higher price point than standard Class C motorhomes, making them a more direct comparison with Class A diesel pushers.
