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.
