Get ready to elevate your RV lifestyle with the stunning 2026 Grand Design Influence 3904BH—a luxury fifth wheel designed for families, full-timers, and adventure seekers who want space, style, and smart functionality all in one. Built by the highly respected Grand Design RV, the Influence series is known for combining residential comfort with road-ready durability, and the 3904BH is one of the most versatile and exciting floorplans in the lineup.
From the moment you step inside, you’ll notice the difference. This wide-body fifth wheel opens up with multiple slide-outs, creating a bright, expansive living area perfect for relaxing, entertaining, or simply enjoying life on the road. Premium finishes, modern décor, and high-end materials give the interior a true residential feel that stands out from the competition.
The kitchen is a centerpiece of the 3904BH, offering everything you need to cook, host, and gather. Featuring solid surface countertops, a large residential refrigerator, deep stainless sink, and ample cabinet storage, it’s designed for real-world use—not just weekend trips. The adjacent dining and living areas provide comfortable seating, a large entertainment center, and plenty of room for everyone to spread out.
What truly sets this model apart is the private bunkhouse suite. Perfect for kids, guests, or even a mobile office, this dedicated space offers multiple sleeping options, storage, and privacy—making it ideal for extended travel or full-time living. Up front, the master suite delivers a relaxing retreat with a king bed, generous wardrobe space, and washer/dryer prep for added convenience.
The bathroom is equally impressive, with a spacious shower, modern fixtures, and plenty of storage to keep everything organized on long trips. Every inch of this RV is thoughtfully designed to maximize comfort and usability.
Built for performance as well as luxury, the Influence 3904BH features a durable frame, upgraded suspension, and high-quality insulation, giving you confidence whether you’re parked at a resort or traveling cross-country. Grand Design’s commitment to quality construction ensures this fifth wheel is ready for years of dependable adventures.
