2023 Jayco Seismic 359 in Baird, Texas

The 2023 Jayco Seismic 359 is one of the most popular floor plans for the Seismic luxury toy hauler. Introduced for the 2022 model year, it provides an ideal combination of weight, capacity, features, and price. It sleeps up to eight people, and thanks to its 11-foot cargo area, it’s more than capable of carrying your OHVs, camping equipment, or other items you need for your next adventure.

Superior Jayco Construction

Like all Jayco RV models, the Seismic 359 benefits from superior Jayco construction and craftsmanship, backed by an industry-leading 2+3 limited and structural warranty. It uses 4,000-lb leaf springs, sturdy Dexter® axles, 5/8-inch plywood floor decking, and the patented Magnum Truss™ roof system that helps protect you from the elements. It’s the strong roof in the industry, in part because it is built out of a single piece of seamless material, which Jayco will back with a 20-year warranty. The Seismic RV also uses vacuum bond laminated walls and rides on 16-inch Goodyear® endurance tires that maintain a stable internal pressure on the go, increasing safety, stability, and even fuel economy.

Comfort all year round

Every Seismic 359 benefits from Climate Shield™ and the HELIX Cooling System™. Together, these ensure that you can make the most out of the camping season, and stretch it even into the hottest or coldest months of the year. Climate Shield uses special PEX plumbing, G20 tinted windows, a heated underbelly, double-layer fiberglass, and double-sided insulation to maintain a stable interior temperature, thus providing year-long comfort. It’s been stress-tested tested in 0 F and 100 F weather, meaning that when combined with the excellent HELIX Cooling System, you’ll never have to look at the temperature forecast and cancel your RV plans.

Upscale interior design

The Seismic is not the most luxurious Jayco RV you can buy, but it’s not far off. It delivers an incredible level of comfort, in large part because of the high quality of the materials and designs. With its solid hardwood cabinet doors, handcrafted and glazed trim and drawers, and American-made residential vinyl flooring, the Seismic 359 feels more like a proper U.S. home than an RV. It’s available in two major styles, Modern Farmhouse and Classic Cottage, both equally luxurious and attractive. Between the residential quilted bedspread, tasteful bathroom tile backsplash, and stainless steel kitchen sink with a pull-out sprayer, you’ll see a side to RVing that few people get to experience.

Ready for cargo

The 2023 Seismic 359 is designed to haul your toys, and there’s more to it than just a large cargo space. To enhance safety and practicality, it features a rubberized garage floor liner and anti-slip, non-skid flooring on the rear ramp door. There are also high-intensity LED ramp lights that you may find useful when storing your quad at night after a day-long adventure. Meanwhile, D-rings mounted to the cargo area’s steel frame add extra convenience you can count on. And if you don’t need the toy hauling capability for a given trip, the HappiJac® electric-lift queen beds and convertible sofa expand the Seismic’s sleeping capacity so you can bring family and friends along without compromising nighttime comfort.

Smart features

The Seismic 359 is packed with smart features that make RV living easier. Every unit features a 4K Smart LED HDTV, a Bluetooth®-compatible sound system, exterior marine-grade speakers, a universal and fully-enclosed docking center (good for quick-connect outside showers or satellite prep), six-point hydraulic auto-leveling system, JaySMART™ LED lighting, and compatibility with the JayCOMMAND™ app that you can use to control virtually every light and function of the RV. There’s also a digital TV antenna with Wi-Fi prep, a heated and massaging sofa, and many more features that you’ll find indispensable after spending time in the Seismic.
