Built on a Freightliner S2RV Plus chassis with a Cummins 6.7L diesel making 360 horsepower and 800 lb-ft of torque, the Jayco Seneca 37M has the bones to haul up to 12,000 lbs on its rear hitch while keeping everyone comfortable inside. The rear bedroom layout puts private sleeping at the back while the over-cab bunk area handles up to 750 lbs, giving the Seneca 37M genuine sleeping capacity for eight. Outside, the entertainment center pairs JBL speakers with an LED HD Smart TV on a swivel bracket, and the Winegard in-motion satellite dish means the show doesn't stop when the wheels do. Owners consistently call the Seneca 37M a standout for its roomy, livable interior, with the Firefly total coach control system, automatic hydraulic leveling, an 8,000W Onan diesel generator with auto-start, and 200W of solar rounding out a feature set that punches well above typical Class C territory.
