Four floorplans are available to choose from. We’ve decided to explore the 3902, which is the perfect space for storing toys, hosting guests and relaxing before an off-road adventure. The 3902 has an uploaded vehicle weight of 14,065 lbs, dry hitch weight of 3,185 lbs, gross vehicle weight rating of 19,000 lbs and cargo carrying capacity of 4,935 lbs. For measurements, the 3902 has an exterior travel length of 42’2”, total exterior length of 44’, exterior width of 102”, exterior height with A/C of 158-3/4” and interior living area height of 102-1/4”.

Built with Jayco’s latest construction advancement, the Seismic features a Magnum Truss Roof System, which Jayco says is 50% stronger than it competitive models. Roof decking is screwed down at each seam, which secures the structure more effectively than stapled construction. Two-by-two vertical studs are strategically placed to maximize load capacity and provide smoother edges for wires. Jayco uses oversized nail plate joint fasteners on both sides of the trusses. Seven-inch header beams are located between the roof and slideout openings. If your camping season last all year, you’ll be thankful for the Jayco Climate Shield. It’s designed to heat and cool your Jayco, and protects it against extreme weather.

When you walk into the Seismic, your eyes will be drawn to the beautiful cabinetry. Amish-crafted cabinets have hidden hinges and ball bearing drawer guides. Appliances surrounding the cabinetry are stainless steel, which make the space look luxurious and modern. The three-burner range has a stainless steel range top with a 9,000 BTU SuperBurner and piezo igniter. When you’re reheating leftovers you can use the 30-inch residential-style stainless steel microwave oven. You can do all your baking in the 21-inch oven. High-gloss, solid surface countertops have an undermount stainless steel sink and sink covers. Dining can take place at the theater seating located across from the entertainment center or in the cargo area, where there are two sofas and a cargo table.

A good indicator of an RV’s luxury is its bathroom. The radius shower comes with colored surround and gives you enough space to move and wash without bumping into walls. The washroom also has a toilet, sink and medicine cabinet. A small cabinet provides extra storage space.

When you need to recharge, lock your doors, shut the blinds and escape to your bedroom. Equipped with a Denver pillow top mattress, the queen-sized bed will put you straight to sleep. If you can’t sleep until you’ve watched your favorite late night show, then turn on the 32” LED HDTV. For storage space, the bedroom is equipped with under-bed storage, wardrobe, and even a walk-in closet. The closet features triple-sliding mirrors. The bedroom is wired and framed for a second air conditioner.
