One look at the Seismic toy haulers by Jayco, and you'll never go back! Each model features a custom automotive-grade vinyl exterior graphics package, a painted fiberglass front cap with built-in LED lighting, and 102" wide-body structural steel I-beam construction. You'll find the pass-through storage with Slam-Latch baggage doors will make unpacking easier than ever, and the rear ramp door/patio with anti-slip, non-skid flooring will allow you to unload your toys with no trouble at all. These toy haulers feature a three seasons garage wall/doors, a 30 gallon fuel tank with a timer, and exterior marine-grade speakers to keep the party going. The Climate Shield zero degree tested weather protection includes a 35,000 BTU furnace, PEX plumbing, and a fully enclosed and heated underbelly so you can enjoy your adventures year around. And we haven't even touched on the interior luxuries you'll find, like solid hardwood cabinet doors, residential vinyl flooring made in the USA, night shades, and more!
