The 170SS includes roomy slideouts and still weighs less than 4,000 lb! Wall-to-wall panoramic windows help to make the extra space seem even roomier, and provide great outdoor views. The front queen bed provides storage access, while the tri-fold jiffy sofa sleeper features a bonus bunk for extra sleeping options. You also get the ever-popular U-dinette, hanging storage closet, pantry, and large bathroom.
