Residential Kitchen With Butler Pantry

At the heart of the Sierra 3900HBLR is a stylish kitchen island with a waterfall edge, providing generous space for meal preparation and serving. Overhead cabinets keep cookware and dishes organized, while the microwave and 12V refrigerator handle everyday meal needs.

A separate butler pantry provides even more storage for groceries, kitchen essentials, and supplies—a valuable feature for extended stays.

Bath-and-a-Half Convenience

A half bathroom gives guests convenient access to their own facilities without entering your private bedroom and front bathroom area.

You'll also find stackable washer and dryer prep here, allowing you to add laundry appliances and reduce trips to campground laundromats during longer adventures.

Private King Bedroom

The bedroom provides a relaxing retreat with a king bed and multiple storage options. A small dresser and tall dresser help organize clothing and personal belongings, while a TV hookup gives you the option to add bedroom entertainment.

Front Bathroom With Walk-In Closet

The spacious front bathroom brings residential-style functionality to the campground. It includes a one-piece fiberglass shower, dual sinks, medicine cabinet, linen closet, and multiple shelves for organizing toiletries, towels, and personal items.

The walk-in bathroom closet provides even more room for clothing and belongings, making this floorplan especially practical for travelers planning longer stays.

Two Awnings for Outdoor Living

Two exterior awnings—one 12' and one 18'—create generous covered space outside. Set up your chairs, enjoy meals outdoors, or simply relax in the shade while extending your living area into the campsite.

Built for the Road

Underbelly Armor helps protect vital components from road debris, while the painted two-tone aerodynamic fiberglass front cap features an improved turning radius. An electric leveling system helps simplify campsite setup.

Additional construction and travel features include a cambered powder-coated frame with rust prohibitor construction, Goodyear radial tires with 7,000-lb. axles, and a TV antenna with booster.

Inside, residential touches include recessed lighting, Beachside Sundance Congoleum linoleum, a memory foam mattress, and hidden-hinge, soft-close drawers and cabinets. A 60,000 BTU on-demand tankless water heater adds another convenience for extended stays.
