2025 Seismic

Starting at $104,655

The Jayco Seismic Toy Hauler is ready to take you and your toys wherever the roads lead. Designed for all-weather camping, the Seismic has undergone zero-degree testing in the Dometic freeze chamber, proving you can camp safely and comfortably all year round, even in snowy conditions. Taking it one step further, the Seismic also undergoes weather chamber testing from zero to 100⁰ F. With Climate Shield™ zero-degree tested weather protection, the Seismic has a fully enclosed and heated underbelly, double-layered fiberglass batt insulation, and double-sided, bubble-foil radiant barrier insulation for best-in-class results. 

Reaching your destination is just as effortless as handling the weather, thanks to the industry-exclusive 4-Star handling package. This innovative package includes a Rota-Flex™ King Pin Box, Dexter® Axles with ABS and sway mitigation, Dexter® Heavy-Duty Shackles with Wet Bolt Fasteners and Bronze Bushings and 17.5” Uniroyal H-rated 16 ply tires. In fact, all of our luxury fifth wheels are built using 7,000-lb. or 8,000-lb. Dexter axles with Nev-R-Adjust® brakes that eliminate the need for time-consuming manual adjustments and greatly improve stopping distances. The Dexter® Heavy-Duty Shackles with Wet Bolt Fasteners and Bronze Bushings help resist the wear and ear of towing, while the Uniroyal tires provide a safer ride, far fewer repairs and much less sway. This means fewer blown tires, less frequent tire replacements, and a longer, happier camping experience. Upon arrival at your adventure destination, the all-new 6,000W generator by NPS powered by Yamaha will guarantee durable, reliable power.

Inside the Seismic Toy Hauler, you’ll experience residential-style living with features like tongue and groove plywood flooring that’s durable and easy to clean, a 30” space saver microwave and a 21” residential-size oven. The smaller microwave allows for more space in the kitchen for storage and highlights the residential sink with built-in glass cleaner and vegetable rinse. In the living area, you’ll enjoy the residential stain guard-protected fabric instead of pleather or vinyl that peels or cracks. 

New for 2025, the Seismic features residential dovetail-jointed drawers for superior strength. These stronger drawers hold more and are more durable so you can enjoy longer camping seasons with fewer repairs. Yet, despite its incredibly durable and rugged build, the Seismic also boasts Jayco’s high-end, custom interior design. Hand-crafted by a team of experts, every fabric, fixture and feature is selected to provide the top-notch livability that Jayco is known for. Because of the attention given to interior design, Jayco is proud to offer higher bunk ratings, thicker bunk mats, slides without carpet—and two interior design options (select products). 

With the Seismic Toy Hauler, you have everything you need for your next greatest adventure.

Jayco uses plywood vs. OSB or other materials because it is more eco-friendly (no formaldehyde), handles moisture better, is lighter in weight and has better screw retention.

The Magnum Truss™ Roof system is one of the strongest roofs in the industry. It's capable of withstanding 50 percent more weight- up to 4,500 lbs.- than the competition so that you can safely perform maintenance and avoid costly structure damage from debris, branches or snow.

Your RV needs a strong foundation built specifically for your floorplan. We build each trailer on a frame that has been specifically designed by our skilled team of engineers for its size and shape to better endure the wear and tear of the road. Our frames also include more outriggers and cross members for better support and structural integrity. 

Jayco uses plywood vs. OSB or other materials because it is more eco-friendly (no formaldehyde), handles moisture better, is lighter in weight and has better screw retention.

Most manufacturers use standard 3500 lb. springs but on all Luxury Fifth Wheels and Toy Haulers we upgrade to the heavy duty 4000 lb. springs for maximum strength.
