Super C Motorhome Manufactures

Super C RVs are a special class of RVs that bridge the gap between Class C and Class A RVs. Like class C, they are built on a truck chassis with the classic truck front profile including a hood and engine in front of the driver. At 33 to 45 feet in length, they offer the space and luxury of many Class A’s.

Super C’s have become increasingly popular over the years and there are now several top manufacturers with excellent units in this category. Here we’ll take a look at eight of these companies and what they have to offer.


Jayco’s entry into the Super C market comes in the form of the Seneca Super C RV. The 2023 Seneca is offered in two different configurations, the Seneca starting at $312,443 and the Seneca Prestige starting at $340,800. Both units are 39’ 4” long, sleep up to 9 people, and come with the build quality you would expect from one of the top manufacturers in the RV industry.

Both units also feature the same chassis and drivetrain with a Freightliner chassis, Cummins 6.7L diesel engine pushing power to the rear wheels through an Allison automatic transmission. This proven, rock-solid drivetrain will provide many dependable years of service.

Both are also available in three floorplans designated as 37K, 37L, and 37M. All of which feature a rear main bedroom but differ in the kitchen layout. The K version has a fixed kitchen whereas the L and M versions have the kitchen in a super slide-out.

The Seneca Prestige builds upon the standard Seneca with the addition of the premium JRide system and more advanced suspension options. This package includes a computer-balanced driveshaft, air suspension in the rear, a rear heavy-duty stabilizer bar, full air brakes, and SACHS shocks. These upgrades significantly improve the ride quality of an already great driving RV.

  3. Force. The Force Super C starts at $344,378 and is available in two lengths – 36’ 8” and 39’ 2”. There are two engine choices, either a 7.7L Detroit diesel or an 8.9L Cummins.
