Cummins ISB 6.7L 340HP Diesel Engine. 3 Slide Outs, Awning, Sleeps 8, 2 A/C Units. Indoor Stored, Motorcycle Lift | Loaded Free and Clear

This 2017 Jayco Seneca 37TS is a premium Super C diesel motorhome that has been stored indoors year-round and carefully maintained. Super C motorhomes have become increasingly popular because they combine the power and durability of a commercial truck chassis with the luxury and space of a Class A motorhome. Many buyers choose Super C models for their superior towing capacity, stability on the road, and easier serviceability compared with traditional Class A coaches.

This coach is built on the Freightliner S2RV, the same type of heavy-duty platform used in commercial trucks. Power comes from the reliable Cummins ISB 6.7, giving the Seneca exceptional pulling power and long-distance durability.

Stronger towing capability than most Class A motorhomes

Truck-style safety and stability on the road

Easier engine access for maintenance

Better handling in crosswinds and mountain terrain

This makes the Seneca especially popular with RVers who tow cars, trailers, boats, or motorcycles.
