Looking to buy a 2026 Grand Design Influence Fifth Wheel RV?

Huge 42′8″ fifth wheel with 4 slides — tons of space to spread out
Sleeps up to 9 — private master up front + rear bunkhouse suite for crew or guests
Massive water & utility capacities (83 gal fresh / 106 gal grey & black), plus tankless water heater — great for longer trips
Upgraded with 3 AC units, king size bed, H-rated Tires w/17.5" wheels
Solar + Package: 330Wpanel & 2000W Inverter
Spacious living room: recliner sofa, theater-style seating, fireplace & entertainment center
Strong build — laminated 5-sided construction, walk-on roof, insulated underbelly, wide-body frame

If you want a fifth wheel that feels like a real home on wheels, the 3904BH absolutely delivers. The front queen bedroom is private and roomy, while the rear bunkhouse gives space for kids, friends, or extra storage. With sleeping for up to 9, you don’t have to squeeze — there’s room for everyone.

The kitchen is legit: full-size fridge, plenty of counter space, and even an outdoor griddle if you want to cook under the stars. Inside, the living area is big — recliners or sofa, a fireplace to cozy up by, TV and entertainment center so nights in feel nice.

Big tanks, tankless hot water, and solid insulation mean it’s not just for weekend trips — you could live in this thing comfortably on long stays. The build is a step above too: strong construction, wide-body design, and all the structural extras that give confidence when you’re on the road.

Bottom line: the 2026 Influence 3904BH gives you space, comfort, and flexibility — a killer option if you want to travel with a crew or just want “home”-level living on the road.
