Built on a Freightliner S2RV chassis with a Cummins 6.7L diesel pushing 360 HP and 800 ft.-lb. of torque, the Seneca 37RB earns its "super C" reputation on the road. Owners consistently say it drives quieter and more confidently than a comparable Class A. The rear bedroom layout keeps living and sleeping space genuinely separated, while the overhead cab bunk adds sleeping room without eating into the main cabin. Outside, the 8,000-watt Onan quiet diesel generator, 190W solar panel with four 6V AGM house batteries, Sani-Con macerator, and an exterior entertainment center with swivel-mounted TV make it as capable dry-camping as it is at a full-hookup resort. Inside, JAYCOMMAND smart controls, vinyl plank flooring, hardwood cabinetry, and 84-inch ceilings give it a premium feel, just know that fit and finish may not quite match the very top tier of the diesel super C segment.
