Spacious Rear Living Room

The rear living area gives you plenty of room to relax and entertain. A comfortable chaise lounge and sofa provide inviting seating, while the entertainment center and fireplace create a cozy focal point for evenings indoors.

A hidden pantry adds valuable storage without interrupting the clean residential appearance. You'll also find a desk with chair, giving you a dedicated place for remote work, trip planning, or keeping up with emails while traveling.

Residential Kitchen With Island

The kitchen is designed to make meal preparation easier during longer stays. A stylish waterfall-edge kitchen island provides valuable prep and serving space, while overhead cabinets help keep cookware and dishes organized.

A microwave and 12V refrigerator handle everyday meal needs, and the separate butler pantry provides even more room for groceries, small appliances, and kitchen essentials.

Convenient Half Bath and Laundry Prep

A separate half bathroom adds convenience when you're traveling as a couple or entertaining guests. Visitors can use their own facilities without entering the private bedroom and front bathroom area.

The half bath also includes stackable washer and dryer prep, giving you the option to add laundry appliances for extended trips or full-time RV living.

Private King Bedroom

The bedroom provides a comfortable retreat with a king bed and dedicated storage. A small dresser and tall dresser give you room to organize clothing and personal belongings, while a TV hookup lets you add bedroom entertainment if desired.

Impressive Front Bathroom and Walk-In Closet

The front bathroom delivers residential-style space with a one-piece fiberglass shower and dual sinks, making morning routines easier for two travelers.

A medicine cabinet, linen closet, shelves, and generous storage help keep toiletries and linens organized. The walk-in bathroom closet provides even more room for clothing and personal belongings, making the 3900HBLR especially practical for extended stays.

Outdoor Living With Two Awnings

Two exterior awnings—12' and 18'—provide plenty of covered outdoor space. Whether you're relaxing with campground chairs, enjoying meals outside, or escaping the afternoon sun, the dual-awning setup helps expand your living area beyond the RV.

Built for Extended Adventures

Sierra equips the 3900HBLR with Underbelly Armor to help protect vital components from road debris. A painted two-tone aerodynamic fiberglass front cap features an improved turning radius, while the electric leveling system helps make campsite setup quicker and easier.

Additional features include Goodyear radial tires with 7,000-lb. axles, a cambered powder-coated frame with rust prohibitor construction, TV antenna with booster, and a 60,000 BTU on-demand tankless water heater.

Inside, residential touches include recessed lighting, Beachside Sundance Congoleum linoleum, a memory foam mattress, and hidden-hinge, soft-close drawers and cabinets.
