For active families on the go, Cub expandable travel trailers add sleeping space without additional length and weight of traditional travel trailers. The Ultra-lite design and aerodynamic profile make Cub a dream to tow. Plus, the interior of Cub is packed with high-end features, including designer decor, large kitchens with abundant storage, expanive living spaces and comfortable sleeping areas. Cub is specifically designed to be towed by most light trucks and sport utility vehicles. Cub's aerodynamic profile is designed to push air up the front wall and over the roof to improve towability and fuel economy. Cub incorporates rubber torsion "indpendent suspension" axles on a European-style frame. Torsion axles allow each wheel to travel independently, unlike leaf spring axles that transfer variations in the road to the opposite wheel. Plus, the torsion axles improve towing stability by lowering the trailer to the ground and reducing the center of gravity.
