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!
