2024 Jayco Seismic | Baird, TX

Floorplans and size

This is a big RV. The shortest model, the Seismic 405, is 41 feet, 5 inches long. The longest model, the new Seismic 399, is just an inch short of 46 feet. And it’s heavy, too, with unloaded weight ranging from 13,220-14,890 pounds.

What this means is you’ll need a heavy-duty truck to get this baby moving. But if you’re in the market for something like a Seismic, then you’re probably a serious camper already and likely have a truck capable of handling it at the ready.

No matter the floorplan — there are five to choose from — you can count on major space and features. The Seismic sleeps 7-9 people and features a cargo area that’s 11-14 feet long, depending on your chosen floorplan. All of the plans have a private, elevated master bedroom with a king-size bed and bathroom, and all even have two available bathrooms.

Built to haul toys

The Jayco Seismic’s main appeal is its garage. Up to 14 feet long without counting the ramp, which features a built-in party deck with stairs, the Seismic has more than enough room for your 4x4s, dirt bikes, and other off-road equipment. And its thoughtful construction provides plenty of storage help. It has a rubberized floor liner to prevent slip, steel frame-mounted D-rings for secure attachment points, and LED ramp lights to enhance your visibility when returning to the RV at night after a long day of fun. You can also count on the six-point hydraulic auto-leveling system to keep all of your gear stable during your camping stays.

Comfortable sleeper

If you’re staying in the master bedroom, enjoy the royal treatment. King-size bed, attached bathroom unit with walk-in shower, spacious chests and dressers, and on some floorplans, even a walk-in closet await — along with washer and dryer prep. But that’s not to say your guests won’t be comfortable. The convertible sofas and HappiJac® electric-lift queen beds make for cozy sleeping accommodations, ensuring that everyone gets off on the right foot when the morning adventures begin.

State-of-the-art conveniences

There’s no shortage of awesome features in the 2024 Seismic. From the Classic Cottage to the Modern Farmhouse interior decors to the bathroom tile backsplash and quilted bedspread, it looks and feels just like a proper home. But there’s a whole lot more to it than just looks. Dual 15,000-BTU A/C systems, thermally-insulated walls and floors, tinted windows, and remote-controlled, power-extendable awnings ensure maximum comfort even during the hottest Texas summers. Residential-grade appliances and luxe kitchen countertops make it a delight to prep meals while camping.

Inside, the available fireplace and theater seating, with heating and massaging, offer a nice reprieve after a long day on your feet. Even better, the stunning number of app-controlled features give you even more reason to keep lounging. You can monitor tank levels, adjust the interior temp and water heater, control generators, extend slideouts and awnings, and more — all using the JAYCOMMAND® app on your phone.
