Be at home wherever you are in the Jayco Seneca. This powerful Diesel Super C has a Freightliner® S2RV Plus chassis, with a Cummins® ISB 6.7L 360HP diesel engine and a 100-gallon fuel tank, which is great for those who want a diesel engine and high tow capacity. With the 100-gallon fuel tank, you'll make fewer stops on long trips, and get to your destination quicker than ever. Our repeat customers rely on the JRide® Premium handling package which features a computer-balanced driveshaft, rear air suspension, a heavy-duty rear stabilizer bar, and SACHS shocks, creating a quiet, comfortable ride that you won't want to end! Of course, we can't forget the full air brakes that provide increased braking power, even on grades, and improve stopping distance. This ensures you enjoy the ride through improved stability and better absorption of road vibrations. In the Seneca, you'll enjoy the journey just as much as the destination. Once you reach your destination, unloading your camping gear to set up camp is a breeze thanks to the carpeted full pass-through basement storage compartments. An optional 12V cooler on a slide-out tray provides easy access to a refreshing drink once setup is complete.
Inside the Seneca Super C, you can take in the view from the Lippert 4000 Series windows with integrated cassette day/night shades, which look just as great from the outside as they do from the inside. Once the sun sets, get to the overhead bunk to enjoy some stargazing through the automotive bonded panoramic window in the front cap. When it comes to the less fun parts of camping, like dealing with the black tank, the Seneca’s Thetford® Sani-Con® Turbo macerator system offers a clean and sanitary way to empty tanks. The built-in macerator ensures no clogs, the power pump ensures you can empty tanks going uphill, and a retractable hose means you don’t have to hook and unhook each time you empty your tanks. The Seneca Super Class C is the epitome of classy.
