Enjoy all the comforts of home wherever you are in the Jayco Seneca. This powerful diesel Super C is built on the Freightliner® S2RV Plus chassis and powered by a Cummins® ISB 6.7L 360HP diesel engine. With a 100-gallon fuel tank, you can cover more ground between stops and reach your destination faster. It’s a great fit for travelers who want diesel performance and an impressive 12,000-pound tow capacity. The JRide® Premium handling package makes every trip smooth and comfortable thanks to a computer-balanced driveshaft, rear air suspension, a heavy-duty rear stabilizer bar and SACHS shocks. Full air brakes provide strong, confident stopping power, especially on grades, and improve ride stability while absorbing road vibrations. In the Seneca, the ride itself becomes part of the adventure.

Once you've arrived at your destination, carpeted pass-through basement storage compartments make unloading gear quick and simple. Extend you electric awning with LED lights right from your phone thanks to the Firefly total coach control system. Once you have shade, open up your exterior entertainment center with JBL® outside speakers and an LED HD Smart TV mounted on a swivel bracket to complete your tailgate or camping setup. You can even add a 12V cooler on a slide-out tray for easy access to a cold drink once you're ready to watch the game or enjoy the campfire.

Inside the Seneca, large Lippert® 4000 Series windows let you enjoy the view while integrated cassette day and night shades add privacy and style. After dark, the overhead bunk becomes the perfect spot for stargazing through the panoramic front window in the one-piece fiberglass cap. Even the less glamorous parts of RVing are easier in the Seneca. The Thetford® Sani-Con® Turbo macerator system offers a fast, clean way to empty your black tank. The macerator helps prevent clogs, the power pump lets you dump even uphill and the retractable hose streamlines the whole process—no need to connect or disconnect each time.

With premium performance and luxury amenities, the Seneca Super C makes every trip feel like a first-class adventure.
