Incredible rear-dinette slide-out floorplan—combines a wide-open interior feel with an outdoor kitchen, panoramic campsite views, and 200W factory solar.
Why We Chose This Wildwood FSX 164RDSK We selected this specific model because it masterfully delivers the wide-open living space of a much larger coach within a highly towable, single-axle footprint. Built by Forest River to maximize comfort on the road, the Wildwood FSX 164RDSK features a deep rear slide-out that houses a massive U-shaped dinette, completely transforming the main living area into a panoramic viewing space surrounded by oversized campsite windows. Up front, a residential-style queen bed offers a comfortable night's rest, while the central kitchen boasts premium appliances and abundant counter space. What truly sets this unit apart is the exterior utility—featuring a fully equipped outdoor kitchen and a large power awning, it is custom-built for open-air entertaining. Complete with a private full bathroom and a tankless on-demand water heater, this nimble travel trailer is engineered for seamless weekend getaways.
Highlights of this Unit:
Expansive Rear Slide-Out: Features a deep roadside slide room that opens up the rear living area, providing an unmatched sense of interior space for its size class.
Premium Outdoor Kitchen: Equipped with a built-in exterior refrigerator and pull-out griddle setup, perfect for maximizing your time out in nature.
Advanced Off-Grid Utility: Comes factory-configured with a 200W roof-mounted solar panel and a high-efficiency 12V refrigerator to keep your camp powered anywhere.

Sumner RV is the place to go!
After losing our 5th Wheel in a fire... we had to go looking for a new RV. We had a height limitation due to where we store RV. Sumner RV had just what we needed for our "dry camping" RV style. Since we were so concerned about size, the sales staff brought an equivalent RV to our home and showed it
