Used 2025 Jayco Seismic 399 — Bossier City, LA

Listed at $55,385, this used 2025 Jayco Seismic 399 is a toy hauler on the Toy Hauler floor plan. Dry weight is 14,950 lb, well above the 8,704 lb median for the category. At 46 ft it is longer than most toy haulers (35 ft 7 in).

Loaded with water, propane and gear it will sit nearer 17,650 lb, which puts it within reach of a one-ton pickup, ideally a dually. Budget for 15–25% of that through the kingpin, and this is firmly heavy-duty territory and the truck matters more than the trailer.

3 slide-outs widen the interior considerably at camp. Sleeping capacity is 8 — more than the 6 typical of the category.

It is listed $31,195 below the $86,580 MSRP, a 36% saving. It sits above the $38,249 category median, reflecting its size and specification.

Among its listed features are auto leveling system, 6kw generator, 4 burner stove and electric patio awning. It ships from Bossier City, LA door-to-door to any of the 50 states, inspected before it leaves, at one transparent price with no dealer fees.
