New 2026 Jayco Seismic 399 — Poteau, OK

This new 2026 Jayco Seismic 399 is a toy hauler on the Toy Hauler floor plan, listed at $59,363. At 45 ft 11 in it is longer than most toy haulers (35 ft 7 in). Dry weight is 14,950 lb, well above the 8,704 lb median for the category.

Plan around 17,650 lb loaded rather than the dry figure. A one-ton pickup, ideally a dually handles it comfortably; this is firmly heavy-duty territory and the truck matters more than the trailer.

Sleeping capacity is 9 — more than the 6 typical of the category. 3 slide-outs widen the interior considerably at camp.

That is a 41% reduction on the $100,802 MSRP — $41,439 off. It sits above the $38,249 category median, reflecting its size and specification.

Fitted equipment includes customer value pkg, five star handling pkg and half bath. It ships from Poteau, OK door-to-door to any of the 50 states, inspected before it leaves, at one transparent price with no dealer fees.
