The expansive 17' garage is one of its standout features, offering a highly versatile space with dual opposing sofas, an independent HappiJac® lift system, and a drop-down bed for additional sleeping capacity. Durable tie-downs with recessed L-tracks make it easy to secure your gear, while the garage loft adds extra storage or sleeping space. With its own entry door and washer/dryer prep, the garage easily transitions from hauling mode to a fully functional living area. Moving into the main living space, you’ll find a refined interior built with Brinkley’s CraftSense™ wood trim construction and residential-inspired finishes throughout. The central living area features a comfortable sofa with four recliners, complete with heat and massage for maximum relaxation. Large windows with integrated blackout shades and reflective insulation help maintain comfort while bringing in natural light. The kitchen is equally impressive, anchored by a large island with pull-out trash bins and a Stow N’ Go paper towel holder. Premium GE Profile appliances, including a 4-burner range, residential microwave, and a 19 cu. ft. refrigerator that remains accessible with the slide in, make cooking on the road feel just like home. Ample cabinetry, a pull-out pantry, and smart storage solutions ensure you’ll have space for everything. Up front, the private bedroom offers a spacious retreat with a king bed slide (or optional queen), a dresser with hidden storage, and washer/dryer prep for added convenience. The adjacent bathroom features a large 30" x 42" residential shower, modern fixtures, and a tankless water heater for endless hot water. Built for extended stays and all-season travel, the Gx 4000X includes triple 13.5K BTU A/C units with heat pumps, a 5,000 BTU electric fireplace, and pet-friendly, carpet-free flooring throughout. With its combination of high-end amenities, thoughtful floorplan, and durable garage setup, this Brinkley toy hauler is ready for everything from weekend escapes to full-time adventures.
