If you’re looking for a fifth-wheel that truly lives like a home, the 2026 Grand Design Influence 3904BH delivers in a big way. Built for families, full-timers, or anyone traveling with a crew, this model combines massive space, luxury finishes, and serious capability for extended adventures.
With a wide-body design and four slide-outs, the interior opens up into a residential-style living space that feels anything but like a camper. The rear bunkhouse suite is a standout feature — giving kids, guests, or even a second living area their own private space. Up front, the master bedroom offers a quiet retreat, while the main living area is built for relaxing with theater seating, a fireplace, and entertainment center.
The kitchen is equally impressive, featuring a large residential refrigerator, expansive counter space, and a layout designed for real cooking — not just quick meals. Add in an outdoor kitchen option and you’ve got flexibility for every kind of camping style.
