**Why We Chose This Black Stone Mountain Series 260KRS **We selected this specific model because it offers an incredibly spacious, dual-slide layout designed for extended stays without towing an oversized trailer. Built right here in the Pacific Northwest on Outdoors RV's signature custom-engineered mountain chassis, the Black Stone 260KRS features a premium rear kitchen layout with massive counter space, a relaxing middle living room slide-out, and a private front bedroom complete with its own dedicated queen bed slide-out and a second exterior entry door. Combined with thermal pane windows, a fully enclosed heated underbelly, and factory-certified four-seasons block foam insulation, this rugged coach handles everything from freezing mountain passes to coastal rainstorms effortlessly.
Highlights of this Unit:
-
Spacious Dual-Slide Living: Maximizes floor space with a deep living room dinette slide-out and a dedicated front bedroom queen bed slide-out.
-
True Mountain Tough Build: Constructed with a heavy-duty, independently certified structural steel frame, rugged integrated A-frame, and off-road suspension designed for rough backcountry roads.
-
Premium Chef's Kitchen: Features a brilliant rear-kitchen configuration with abundance of solid surface countertops, a deep farm sink, a kitchen pantry, and a sunken range with a glass front.
**The Sumner RV Difference **When you partner with Sumner RV, you are joining a 60-year legacy of integrity. As a family-run dealership hand-picked by the Nash family to carry on their tradition, we prioritize long-term customer relationships over transactional sales. To guarantee your absolute peace of mind, we invite new owners to spend their first night right here on our property along our year-round salmon creek—ensuring you are 100% comfortable with every feature before you head out to see Mt. Rainier.
