Venture RV’s single axle Sonic Lite offers solid construction, with floorplans starting out at a fuel-saving 3,000 pounds! Sonic Lite features the most interior storage in its class. Interiors are surprisingly spacious – there’s ample storage and Lite boasts many of the same features as Sonic, on a more compact scale. Both Sonic Lite and Sonic are engineered with a one-piece seamless fiberglass roof system. By arching the roof front to back, this system provides a more durable roof. When it rains, the water runs fore and aft.
