That Cummins ISB 6.7L diesel pumping out 360 HP and 800 ft-lb of torque is the headline here. Owners consistently say it "rides like a dream" and handles heavy towing without breaking a sweat, backed by an Allison 3000 MH transmission and a 12,000-lb rear hitch. Three slides open up a genuinely home-like interior with 84-inch ceilings, vinyl plank flooring, and raised-panel hardwood cabinetry, while the overhead cab bunk (rated to 750 lbs) adds real sleeping capacity without crowding the living space. For boondockers, the package is surprisingly capable: four 6V AGM house batteries, a 190W solar panel, an 8,000-watt Onan quiet diesel generator with auto-start, and a 100-gallon fuel tank mean you can stay off-grid without much compromise. The exterior entertainment center, in-motion satellite dish, and Thetford macerator system round out a build that's clearly designed for long-haul, self-sufficient travel.

Travel with the power of a diesel coach and the comfort of a luxury RV in this USED 2019 Jayco Seneca 37TS Super C motorhome.

Power is delivered through an Allison 3000 MH automatic transmission, giving this Super C the drivetrain many RVers want for long-distance travel and towing.
The 37TS triple-slide floorplan opens into an impressive living area with a king bed, cab-over bunk, residential refrigerator, solid-surface countertops, large entertainment system, full bathroom, and multiple sleeping areas. At approximately 38' 9" long with a 29,000-lb. GVWR, this is a substantial diesel motorhome designed for serious travelers.

Other listings for this floor plan, ranked by condition, model year, distance, price, and listing quality.
Jayco's 2019 literature confirms the 37TS floorplan's king bed, residential refrigerator, 50-inch TV lift, 17-foot awning and outside entertainment center, while published 2019 specifications list the Freightliner S2RV chassis, Cummins 6.7L diesel, 360 HP, Allison transmission and 29,000-pound GVWR.
Because this is a used 2019 motorhome, exact installed options, mileage, generator hours, equipment, furnishings and current condition should be verified on this specific unit.
The Jayco Seneca 37TS is for RV buyers who want more capability than a conventional gas Class C without moving into a traditional diesel-pusher Class A.
Underneath the coach is a Freightliner S2RV chassis paired with the Cummins ISB 6.7L diesel and Allison 3000 MH transmission. The 2019 37TS carries a 29,000-pound GVWR, while the factory configuration included a 12,000-pound-rated hitch, making towing capability one of the major attractions of this Super C platform.
That makes the Seneca especially appealing to travelers who want to bring along a vehicle, trailer, boat, or recreational equipment, provided all actual loaded weights remain within the coach's ratings.
One of the strongest selling points of the 2019 Jayco Seneca is what's underneath it.
The 6.7L Cummins diesel produces 360 horsepower and 800 lb.-ft. of torque, paired with the Allison automatic transmission. The chassis also incorporates features such as full air brakes, rear air suspension, heavy-duty stabilizer components, and an engine exhaust brake.
For buyers planning long highway trips, mountain driving, or extensive RV travel throughout the West, the combination of Cummins, Allison, and Freightliner is a major reason to consider a Super C.
Once you arrive at the campground, the three slide-outs dramatically expand the 37TS interior.
Dual opposing slides in the main living area create an open residential feel with plenty of space between the seating and kitchen. The floorplan incorporates a hide-a-bed, dinette, residential refrigerator, kitchen workspace, entertainment center with 50-inch TV lift, and additional sleeping space above the cab.
It's a layout built for travelers who want enough room to comfortably spend weeks—or longer—on the road.
The Seneca's kitchen provides considerably more functionality than the compact galley found in many Class C motorhomes.
The 2019 Seneca featured solid-surface countertops with a pull-out extension, residential refrigerator, stainless kitchen appliance package, and substantial cabinetry and storage.
With a residential refrigerator, convection microwave, cooking appliances, pantry storage, and generous counter space, the 37TS is well suited to extended trips where you're actually preparing meals inside the coach rather than relying on restaurants every night.
At the rear of the coach is a dedicated master bedroom featuring a 72" x 80" king bed.
The bedroom provides substantial wardrobe and clothing storage along with dedicated bedroom entertainment. The floorplan also offers washer/dryer preparation, adding another valuable feature for extended travel.
For couples planning longer trips or spending significant portions of the year traveling, having a genuine king bedroom and substantial storage can make the Seneca feel much more like a home on wheels.
A diesel motorhome needs serious onboard power, and the Seneca was equipped accordingly.
The 2019 coach included an Onan 8,000-watt Quiet Diesel generator with automatic generator start, 2,000-watt pure sine wave inverter, 50-amp electrical service and electric power cord reel.
That gives owners the ability to operate major coach systems when shore power isn't available—an important advantage for travel days, dry camping, overnight stops, and extended road trips.
Published 2019 specifications list a 100-gallon diesel fuel tank, 72-gallon fresh water capacity, 40-gallon gray water capacity, and 50-gallon black water capacity.
Those larger capacities complement the Seneca's long-distance design and make it much better suited to extended travel than a small Class C or conventional camper van.
The 2019 Jayco Seneca 37TS is an excellent match for travelers who want to explore Wyoming and the American West without giving up residential comfort.
From Yellowstone National Park and Grand Teton National Park to the Bighorn Mountains, Colorado, Montana, Idaho, Utah, and destinations across the country, the Seneca provides the power and amenities needed for serious road trips.
Its diesel drivetrain is especially attractive for travelers who expect to encounter long highway grades, mountain passes, and substantial towing demands.
The Seneca combines several highly desirable names in one motorhome: Jayco, Freightliner, Cummins, and Allison.
Add in the triple-slide floorplan, king bed, residential refrigerator, diesel generator, substantial towing capability, full-body paint, exterior entertainment, large fuel capacity, and residential-style interior, and it's easy to understand why used Seneca Super C motorhomes remain attractive to serious RV travelers.
For buyers comparing a used Super C motorhome, diesel Class C, Freightliner motorhome, Cummins diesel RV, or luxury diesel motorhome, the 2019 Seneca 37TS deserves a close look.
