The largest of the Jayco Class C motorhomes is the Seneca. Built on a diesel Freightliner chassis, the Seneca has the power to take you anywhere with ease, and the 12,000 pound towing capacity make the Seneca the perfect partner in work or play! Large storage bays, exterior entertainment center, JRide suspension upgrades, and 50 amp service are just a few of the fantastic standard features on the Seneca. With beastly power and tons of room you may think the Seneca would be intimidating to drive, but it is easy for all levels of RV drivers. Check out our Jayco Senca inventory below!
