When you think of full-time fifth-wheel living, you expect comfort, quality, and craftsmanship that go above and beyond. The 2026 Grand Design Solitude Influence 3904BH delivers all of that and more — offering a perfect blend of residential comfort, innovative design, and rugged durability. Designed for travelers who refuse to compromise on luxury or functionality, this fifth wheel takes the concept of family-friendly living to new heights. From the dual suite layout to the expansive outdoor kitchen and industry-leading construction, every inch of the Solitude Influence 3904BH is built to impress.
The 2026 Solitude Influence 3904BH commands attention from the first glance. Grand Design has long been known for its uncompromising exterior construction, and the 3904BH continues that legacy with a fully laminated sidewall system, high-gloss gel-coated fiberglass exterior, and an aluminum cage frame that ensures strength without unnecessary weight. The drop-frame chassis design increases storage space, while the rubberized pass-through storage compartment provides ample room for all your outdoor essentials.
Equipped with dual power awnings with LED lighting, friction-hinged entry doors, and slam-latch baggage doors, convenience meets sophistication. The color-matched fiberglass front cap with integrated LED accent lighting gives the Solitude Influence a sleek, automotive-inspired profile that turns heads whether you’re at the campground or parked lakeside.
The MORryde CRE3000 suspension system with heavy-duty shackles and wet bolts smooths out the bumps on even the roughest roads, while G-rated tires and 16-inch aluminum rims provide stability and long-term durability. Hydraulic auto-leveling jacks come standard, ensuring a fast, effortless setup every time you arrive at your destination.
For those who love extended stays, the fully enclosed and heated underbelly keeps tanks and lines protected, and the dual 15,000 BTU whisper-quiet A/C units work in tandem with the 35,000 BTU furnace to maintain ideal temperatures in any climate. This fifth wheel isn’t just made to travel — it’s designed to let you live anywhere in comfort.
The Solitude Influence 3904BH recognizes that some of life’s best moments happen outside. The outdoor kitchen makes it easy to enjoy meals under the open sky with a built-in mini refrigerator, two-burner cooktop, cabinet storage, and solid-surface prep space. Whether it’s a weekend barbecue or a quick breakfast before a hike, the outdoor kitchen transforms your campsite into a culinary retreat.
Add in marine-grade exterior speakers, LED awning lighting, and satellite/cable hookups, and you’ve got the ultimate entertainment setup ready to go at the push of a button. The optional rear-mounted grill and exterior TV bracket further elevate your outdoor experience.
Step inside the 2026 Solitude Influence 3904BH and you’re immediately welcomed into a residential haven that feels less like an RV and more like a luxury home on wheels. At 43 feet in length, this fifth wheel maximizes livability with a front master suite, a rear bunkhouse suite, and two full bathrooms — a rare and coveted combination for families or traveling companions who need privacy and convenience.
The open-concept living area is the heart of the 3904BH. Grand Design’s signature tall ceilings and oversized panoramic windows create a sense of openness, bathing the space in natural light and offering breathtaking views of your surroundings. Plush Thomas Payne theater seating with heat, massage, and LED accent lighting provides the perfect spot to relax after a day of exploring, while the tri-fold sofa converts easily into an additional sleeping area for guests.
A large entertainment center features a high-definition Smart TV, JBL sound system, and a 40-inch electric fireplace that adds both warmth and ambiance. Whether it’s a rainy evening movie marathon or a cozy night in, this living area caters to every mood.
Adjacent to the living room, the 3904BH’s kitchen is designed for both the chef at heart and the busy family on the move. The solid-surface countertops, residential stainless steel sink with pull-down sprayer, and real wood cabinetry showcase the attention to detail and craftsmanship that defines Grand Design.
A residential 18 cu. ft. refrigerator (12V or optional residential electric model), three-burner range, oven, and microwave convection oven give you all the tools needed to prepare gourmet meals wherever you roam. The large kitchen island doubles as both a prep area and social hub, offering bar-style seating perfect for casual dining or morning coffee.
Storage is abundant, with deep drawers, a pantry with motion-sensor lighting, and overhead cabinets finished in rich tones. Even small touches like the soft-close drawers, hidden hinge hardware, and under-cabinet lighting emphasize the luxury-grade experience.
Up front, the master bedroom exudes tranquility and sophistication. The king-size bed (with an optional queen configuration) is set within a slide-out to maximize floor space, surrounded by beautifully crafted cabinetry and full-length mirrored wardrobes. A dresser with drawers, under-bed storage, and prep for a washer and dryer ensure that the space is both functional and comfortable for extended travel.
Above, accent lighting, reading lamps, and quiet A/C ducting make for a serene retreat, while the solid wood sliding door provides privacy when you need it. The front walk-in closet is large enough to rival residential spaces, complete with shelving and hanging rods for clothing organization.
The master bathroom, accessible via the bedroom, features a spacious fiberglass shower with glass doors, porcelain foot-flush toilet, solid-surface vanity, and skylight. Every finish, from the chrome fixtures to the tile-style backsplash, adds to the high-end feel.
The 3904BH’s rear suite redefines what families can expect in a fifth wheel. Perfect for kids, guests, or multi-generational travelers, this private area features dual opposing slides, creating a massive open space. The bunk configuration includes a tri-fold sofa, loft-style upper bunk, and entertainment center with TV prep and wardrobe storage.
The real standout here is the private rear bathroom, complete with its own shower, vanity, and toilet, plus direct exterior access. That second entry door means no more tracking dirt through the main living area — ideal for families coming in from outdoor activities or pets needing a quick wash-up.
This separate rear suite makes the Solitude Influence 3904BH one of the most versatile and family-oriented models in Grand Design’s lineup, catering to everyone’s comfort and privacy without compromise.
The 2026 Solitude Influence 3904BH is packed with thoughtful features that make life easier for modern RVers. The Compass Connect control system allows you to manage lighting, slides, awnings, and tank levels from your smartphone. Motion-sensor lighting in storage areas and hallways ensures you’re never fumbling in the dark, while the central vacuum system makes quick cleanups effortless.
The whisper-quiet A/C system, featuring dual 15K units with independent ducting, minimizes noise while maximizing airflow. The 50-amp electrical service and solar prep package offer flexibility for off-grid adventures, while the inverted outlets keep your essentials powered wherever you go.
USB charging ports, abundant 110V outlets, and integrated wireless charging pads keep your devices ready for adventure. Add in heated holding tanks, LED lighting throughout, and residential insulation (R-40 roof, R-45 floor, R-11 walls), and you have a fifth wheel designed for all-season travel.
Grand Design has built its reputation on superior construction standards, and the 2026 Solitude Influence 3904BH exemplifies that commitment. Every unit is tested through multiple quality-control stages to ensure unmatched reliability.
The laminated aluminum-framed sidewalls, wood-truss roof construction, and double-insulated floors provide exceptional strength and thermal efficiency. The TPO walkable roof membrane resists cracking, chalking, and fading for years of protection.
Grand Design’s Rail-Tite™ underbelly seal system ensures no gaps between frame and flooring, keeping rodents and debris out. Combined with the fully enclosed underbelly, this design maintains consistent interior comfort and protects your investment from the elements.
The Solitude Influence 3904BH doesn’t just provide comfort — it offers incredible practicality for full-timers and long-haul adventurers. The pass-through storage compartment with motion lighting, slam-latch doors, and aluminum framing provides more than enough room for outdoor chairs, tools, and recreational gear.
Inside, deep cabinetry, pantry shelving, closets, and hidden storage nooks ensure that everything has its place. Grand Design’s attention to detail extends even to the rear storage bay and utility center, where you’ll find neatly organized water controls, an outdoor shower, and an easy-access winterization panel.
Operating a luxury fifth wheel like this should be simple, and the 3904BH makes it so. The auto-leveling hydraulic system takes the guesswork out of setup. The dual 30-lb propane tanks offer ample fuel for cooking and heating, while high-capacity fresh (93 gal), gray (100 gal), and black (106 gal) tanks support longer boondocking adventures.
The 50-amp power service, converter, and solar prep system allow for flexibility in power sourcing. Add Grand Design’s optional Solar Plus package, and you can expand your energy independence with upgraded panels, charge controllers, and lithium battery options.
Grand Design puts safety at the forefront with independent brake systems, steel-reinforced entry steps, backup camera prep, and LP/CO/smoke detectors strategically placed throughout the unit. The all-steel drop-frame chassis by LIPPERT provides unmatched structural integrity, and each Solitude is backed by Grand Design’s industry-leading 3-year limited structural warranty.
The Solitude Influence line bridges the gap between high-end luxury and attainable value. While maintaining the sophisticated styling and robust construction of the flagship Solitude series, the Influence line trims excess weight and cost without sacrificing livability. The 3904BH, in particular, delivers an outstanding layout that perfectly balances private bedroom suites, high-capacity storage, and entertainment options — all within a striking design that feels more like a modern home than a camper.
From the rich residential vinyl flooring to the accent lighting and matte-finished cabinetry, the 2026 Solitude Influence 3904BH surrounds you in elegance. Every texture, finish, and lighting choice is intentional — designed to enhance comfort and highlight Grand Design’s craftsmanship.
