**Why We Chose This Black Stone Mountain Series 250RDS **We selected this specific model because it offers the ultimate balance of spacious living and extreme, all-weather utility for long-term travelers. Built right here in the Pacific Northwest on Outdoors RV's signature custom-engineered mountain chassis, the Black Stone 250RDS features a massive rear-dinette layout surrounded by panoramic windows that pull the beauty of your campsite right inside. Combined with thermal pane windows, a fully enclosed heated underbelly, and factory-certified four-seasons block foam insulation, this rugged coach is purposely built to withstand everything from freezing mountain passes to extended off-grid boondocking.

Highlights of this Unit:

• Panoramic Rear Dinette (RDS): Features a comfortable, oversized U-shaped booth dinette positioned under massive rear and side windows for unmatched campsite views.

• True Mountain Tough Build: Constructed with a heavy-duty, independently certified structural steel frame, off-road suspension, and rugged Goodyear tires designed for backcountry towing.

• Extended Stay Comfort: A smartly split bathroom layout leads into a private front walk-around queen bedroom with abundant wardrobe storage and a dedicated exterior entry door.
