For those who want to go RVing in a motorhome but need to be able to tow, many choose what is referred to as a Super C motorhome. And that is what today’s review of the 2025 Jayco Seneca XT 35L is all about. Coming in based on Ford’s F600 platform, the Seneca XT 35L gives you a gross combined weight (truck and trailer) of 34,000 pounds. This RV really makes sense for those towing larger boats, car haulers, or horse trailers. And the upgraded four-wheel-drive features in this rig support those uses as well.
There was a lot to like in the Seneca XT 35L. But I did also see one potential cautionary aspect that could affect the off-roading experience in this RV.
So, let’s get started and talk about everything.
At a Glance: Seneca XT 35L
Powered by a 7.3L diesel engine that drives all six wheels and with a lifted chassis on aggressive wheels, the Seneca XT 35L might instantly appeal to campers who seek adventures far away from civilization. But one step inside may surprise you. There, you’ll find a premium feeling rig with comfortable seating and an inviting interior.
Jayco has also done something interesting with the power system. There are two alternators fitted to the engine, so that you can idle the engine to charge up the house batteries. There’s also a 6,000-watt diesel generator on board. In addition, there are 200 watts of solar on the roof with the ability to add more capability based on your camping style.
I gave the Jayco Seneca XT 35L a rating of three and a half out of five.

Safety Features and Handling
- Jayco’s J-Ride system improves ride and handling by upgrading suspension and handling pieces. It also along adds dampening in the steering system to improve both comfort and control in this RV. Handling is a common complaint in RVs and Jayco’s improvements go a long way toward correcting this. The steering dampener, for example, reduces the amount of corrections you have to make while driving which makes for a more relaxed journey.
- Some drivers may be intimidated by driving something like this. Others, who might also have an F-Series truck from Ford, can sometimes forget there’s an entire motorhome back there. The full camera suite on this allows the driver to see the exterior of the vehicle and the obstacles. I particularly like that the rear-view camera’s display is in what looks like a rear-view mirror, which is a natural place to look for most drivers.
- Modern vehicles have a lot of safety technology. They commonly include things like electronic controls that help with sway due to sidewinds, anti-lock braking, collision mitigation, and more. This platform inherits those from Ford making the journey a bit safer.
- While not mandated by federal motor vehicle safety standards, Jayco goes the extra mile by putting lap belts at every seating position, including rear-facing seats such as in the booth dinette. Something I haven’t seen in any other brand of motorized RV is the use of child safety seat restraints. But you’ll find two of them in this RV in the forward-facing seats in the dinette. This makes it possible to bring along much younger campers. (And, of course, to indoctrinate them into the RV lifestyle.) Honestly, many people discover too late that the motorized RV they bought has no provision for child safety seats and have to figure out some other way of transporting very young future RVers.
Quality Assurance
- While many RVs use decals to add some texture to the exterior styling, this one uses full body paint. It’s the same kind you would have on your own personal vehicle. This finish is much less susceptible to deteriorating over time from the natural environment and offers a high-end appearance to this rig. While I don’t like to comment on styling, since it’s so subjective, I will say I was really intrigued by the Desert Storm and Backwood Adventure paint packages.
- Jayco has one of the best strong warranty packages in the industry with two years comprehensive and three years on the exterior build.
- Something we saw when visiting Jayco was their predelivery inspection facilities. Every single Jayco product goes through these facilities with hundreds of points of inspection on motorized rigs. While no RV is perfect, having a thorough inspection of the finished rig before it ever leaves the property does help ensure that an RV will have fewer issues initially.
Inside
- While there is propane aboard this RV, the kitchen is all-electric. The way Jayco implemented this was with a two-burner induction cook top and a larger convection microwave. While some cooks say they don’t like cooking on electric, using induction cooking is a whole different beast. It’s also something I’ve switched to in our own home and would switch to in our RV given the chance. Not having an open propane flame for cooking means you don’t heat up and stink up your RV as much. And cooking can be quicker.
- There are a lot of interior details and appointments that really feel premium in here. Among the most notable are the audio system, that induction cooking arrangement, and the fact that this includes a combo washer-dryer.
- A macerating toilet is a unit that literally is like a food processor. (But, you know, sort of at the end of food’s life rather than in the prep stage.) The advantage of this is that you can use a smaller hose for waste disposal. You can also use this system to pump the contents of your black tank uphill.
Challenges
- While this rig has a formidable and aggressive off-road appearance, the leveling jacks below the cab of the rig would really be a cause of concern for me if I were going off-road. When retracted, these still extend fairly close to the ground and that would limit the number of places you could go if you’re planning on going off-road.
- Some campers will not like the split bath. For those who don’t know, a split bath is where the shower is on one side of the aisle and the sink and toilet are on the other. The door from the lavatory can be used to close-off the hallway and provide privacy. While it does have a magnetic hold-back to secure it when propped open, that won’t stop any rambunctious junior rangers from bursting through to see who’s in the shower.
Best For
- Super C shoppers who want to tow larger boats, vehicles, or horse tailers
- All-terrain RVers aiming to go off the beaten path
Key Areas of RV Trader Reviews
RV Trader asked RV shoppers what was most important to them in their RV buying process. Potential buyers — like you — helped us to identify a list of six key areas that camping and travel enthusiasts always look at when they’re searching for the perfect RV: sleeping space, bathroom, living area, four-season capabilities, and storage space.
The RV Trader team then got to work providing you with an honest and unbiased evaluations. And that’s where I come in. I’m Tony Barthel, RV expert and enthusiast. I provide an honest look at RVs from an RV industry insider perspective. That way, you can learn the good, the bad, and the intriguing about any RVs I review. I inspect each RV with the buyer’s perspective at the forefront. And I always evaluate those six key areas that buyers have told us that they have in mind.
So, that said, let’s take a closer look at the 2025 Jayco Seneca XT 35L.
Sleeping Space
Jayco has really stepped-up with the bunks over their cabs. And the Seneca XT 35L is no exception with a two-person bunk over the cab of this rig that can support 750 pounds. While I doubt that you’ll find two friends to come along who amass that much heft, this over-building is part of why Jayco products have such a long warranty. One thing to note: The nose of this space slopes down so the person toward the front of the cab-over bed is going to have a bit of a tight spot.
There are two seating options in this rig. You can opt for theater seats or a jackknife sofa. If you choose the jackknife sofa, that adds two more sleeping positions to the equation. Which is really nice if that’s important to you.
The dinette, too, can fold into a bed for two but they would likely be two smaller travelers as this space measures 38 inches by 70 inches when in sleep mode.
A Suite Surprise
Lastly, the folks paying the bills get the best sleeping arrangement in a 72-inch by 80-inch bed with a bed lift. That means the head of the bed can tilt up. Conveniently, that makes it great for watching the second TV (included). Or for just relaxing in front of the electric fireplace. When the head is tilted up, it reveals a cushioned platform. Which makes it a nice place to sit and put on shoes or just contemplate the day ahead.
Bathroom
As mentioned, the bathroom in the Seneca XT 35L is split with the toilet and sink on the road side of the hallway and the shower on the camp side. The bathroom door from the toilet room can close off the front of this RV with a magnet. There’s also a sliding door from the bedroom side. So, you can close off the bathroom from this direction as well.
With the two doors closed, this offers a pretty spacious bathroom. And there’s a good counter in the bathroom along with a bit of storage. This type of configuration maximizes the usefulness of the bathroom space, while minimizing how much length it consumes in the RV overall.
Living Area
As soon as I stepped into the Seneca XT 35L, it felt very spacious. Some of that has to do with the 84-inch ceiling height. But the way the kitchen wraps around, and the overall positioning of the pieces, just gives it an open feeling. The cabin has a quality feel to the cabinets and furnishings in here right down to the padded ceiling, which helps both with insulation and with noise canceling.
The main seating space, either a jackknife sofa or theater seats, is directly opposite a booth dinette over on the camp side of this rig. There are a good number of windows in this RV, so you get good views of what’s outside. There is also a televator at the dinette. So, if you want to catch up on your soap operas or see the latest reruns, just push a button. The TV will glide up out of its space like a phoenix of entertainment rising … from Arizona. (Thank you, Frank Costanza.)
Kitchen
The kitchen in the Seneca XT 35L is at the back of the main living space. The counter runs partially along the road-side wall and across the back. There is a lot of counter space in here with the sink along the back wall in the shadow of a really fancy stone-look backsplash.
Along the road-side counter is that two-burner induction cooktop. It is flush-mounted with the counter, so it could be counted as additional counter space when you’re not cooking. As it is, there is quite a decent amount of counter space in this RV. So, food prep is going to be a highlight.
Cooking with Style
Either because of the induction cooktop or the style of windows in this rig, you don’t have those annoying metal miniblinds behind the kitchen, which are actually part of fire code. This makes the whole kitchen space seem cleaner and more modern. And there is a large window here which opens for air flow.
There is a good amount of cabinet and drawer space in here. Which is fortunate, because it means that storage is not a challenge. Plus, there is a double pantry as well.
The model I saw had a Samsung residential refrigerator, but I would prefer the available 12-volt RV-specific choice. You don’t need to run the inverter for the 12-volt fridge to operate. There is also an included water filter that can filter both incoming water as well as filter the water you pump out of the fresh water holding tank.
Four-Season Capabilities
This camper features a heated and enclosed underbelly along with 12-volt tank heating pads. Jayco claims this helps prevent freezing down to negative 11 degrees Fahrenheit. The baggage compartments are also built with thicker doors to better insulate the passthrough storage bays.
Storage Space
Another highlight of the design of this camper is storage. There are passthrough storage bays along almost the entire length of the Seneca XT 35L with slam latches. Many of these bays pass through to the other side for the camper, although the passthrough space has to navigate the frame rails. So, it is narrower at the top.
Inside the RV itself, there is a good amount of drawer and cabinet storage in the main living area. There’s also almost a full wall of storage in the back bedroom with plenty of drawers and cabinets.
For those who don’t plan to utilize the over-cab bunk, you could use this for additional storage as well. (Which I’ve seen lots of owners of Class C RVs do. _ With 750 pounds of weight carrying capability, this over-cab bunk might be just the place to keep your baby hippopotamus that you got after hearing that song at Christmas.
Closing Notes on the Seneca XT 35L
There are a few more things to take note of here. The windows in the Seneca XT 35L have been changed for 2025 to ones that incorporate both bug screens and shades into the actual build of the window. This eliminates the window trim/valances around the window and just offers a much cleaner appearance. You also have the ability to fully cover the window with the pull-up bug screen when it’s open. But that also ducks away when you don’t need it. There’s also an effective shade that drops down and has thermal insulation on the backside to keep heat or light out.
On the exterior of the RV these windows are a frameless design. This protects the seals and requires less maintenance while also offering a cleaner look. I like these quite a bit.
Also, on the subject of openings, this is the first time I’ve seen Lippert’s new screen door which incorporates the shade to cover the door window. What this accomplishes is that you don’t have to open the screen and door. Close the screen. Then pull the shade over the window. And then repeat the process. (Ugh. I’m already tired.) In the Seneca XT 35L, you can also just pull the shade down when the door is closed, since it’s inside the RV rather than on the back of the door. Really, I wish this were a universal feature. It just makes so much sense.
My Starlink Musings
One more thing. This RV comes with a Starlink installation. Hear me out on this: I think that’s silly. The reason I write that is that the people for whom Starlink makes sense likely already have a dish. For example, I wrote this review and uploaded it via Starlink. But I wouldn’t permanently mount it to my RV because there are times that I’m parked under trees which really challenges Starlink’s ability to perform. What I would rather see is a port system where owners or Starlink or other things like that can have a port to the pass-through basement storage to feed wires. This would also facilitate easier adding of solar.
Inside the Super C Society
The place where I’ve seen these Super C RVs most is at equestrian events where their significant towing capabilities can handle Mr. Ed and his trailer with ease. Another popular place I’ve seen these is at automotive events is where the trailer with the race car, tools, and spare tires are towed to the event.
There are lot of features that will be great off-road, and that’s kind of the Seneca XT 35L’s persona. But while the aggressive lift and front bumper kit plus ultra-bright lighting and other components may scream “let’s go off-roading,” take your own look at that leveling jack sticking down under the cab. To me, it says, “not on my watch.”
Truly, the appearance of this RV really is striking with the additional height and front bumper guard being part of that story. The changes Jayco made for 2025 to include the newer style of windows, the better shade/screen system on the entry door and a few other things really will make owners happy over time.
