2027 Seneca

Starting at $380,693

The Jayco Seneca is a powerful diesel Super C built on the Freightliner® S2RV Plus chassis powered by a Cummins® ISB 6.7L 360HP diesel engine. This chassis includes a 100-gallon fuel tank allowing for fewer stops on the way to your final destination. This Super Class C is perfect for those wanting a diesel-powered motorhome with luxury amenities creating a like-home feeling on the road.

The JRide® Premium ride and 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. The components that make up the JRide® Premium package reduce vibration, keep the motorhome stable on uneven surfaces, reduce body roll and provide confident stopping support overall, reducing driver fatigue during longer trips and providing a comfortable ride. In the Seneca, the ride itself becomes part of the adventure.

This year, experience new interior design packages that provide a modern feel. There are two fabric packages and two cabinetry colors to choose from to ensure your motorhome matches your personal taste.  

With premium performance and luxury amenities, take home with you wherever the open road leads you in the Jayco Seneca Super Class C.

Seneca Floorplans and Prices

The Seneca Super Class C offers a comfortable, roomy ride with unbridled power. With three floorplans all measuring 39' 4" in overall length, choosing the right floorplan comes down to the most comfortable configuration for you and your travel companions.

 If a bath and a half is a must, you'll want to opt for the 37K. This floorplan sleeps up to 6 and features a large kitchen and a 93 in. reclining sofa across from an entertainment center with a 40 in. TV and fireplace.

The 37M sleeps up to 8 and is incredibly spacious due to opposing slides in the living room and bedroom. Not only does the extra space make this floorplan great for entertaining, but with power theater seating, a jack-knife sofa and a booth dinette there is plenty of space to gather with those you love the most.

For those wanting dedicated bunks, the 37L sleeps up to 9 in comfort and style. The full bathroom is centrally located so everyone has easy access. The master bedroom is still private as there’s a pocket door to separate from the rest of the sleeping spaces.

Enjoy a quiet and comfortable drive thanks to this powerful blend of ride and handling features. JRide® Premium upgrades on the Seneca include:

 - Computer-balanced driveshaft

 - Rear air suspension

 - Heavy-duty rear stabilizer bar

 - Full air brakes

 - SACHS shocks

Jayco RV's StrongholdVBL® vacuum-bond process applies 144 tons of pressure to wall components (fiberglass exterior siding, welded aluminum framing, block foam insulation, metal backers and interior wall panels) for 16 to 18 minutes for an incredibly strong and durable product. All sidewalls, floors and roofs are built by Jayco RV in a temperature and humidity-controlled facility.

The Seneca's one-piece, seamless front cap resists wear and tear like fading or moisture damage over the years. An automotive-bonded panoramic window with a power shade in the front cap lets in plenty of natural light.

A crowned one-piece fiberglass roof provides unmatched durability.

The overhead bunk in the Seneca boasts a weight capacity of 750 lbs. This is 300 lbs. more than the industry standard and allows owners to sleep two full-sized adults or store extra gear while traveling.

Not only is solar power environmentally friendly, but it also reduces the cost and load of electrical use in your motorhome. A standard 200W solar panel with a dual controller will monitor and charge your house and chassis' batteries simultaneously.

Easily access all of your gear with the Seneca's carpeted, full pass-through storage compartments with lockable Slam-latch™ doors

Seneca's dual-pane, tinted safety-glass frameless windows make exterior maintenance easier than ever and give the motorhome a sleek, modern look.
