Other floor plans with a similar body style, feature mix, and price range, prioritizing other manufacturers and brands.
Two entry doors, bunk beds, a loft, and a kitchen island with pendant lighting. The 3900DBL packs a lot of livable space into its wide-body frame without feeling like a maze. The front bedroom and rear bath layout keeps the living area open, and the 5.5K BTU electric fireplace with thermostat and remote adds a touch of comfort you don't always see at this price point. Outside, the heated enclosed underbelly, dual-layer insulation, and thermal package rated from 0–100°F mean this rig isn't just for summer trips. Thomas Payne furniture with theater seating, solid surface countertops, and an outside kitchen round out a package that's built for extended use, not just weekends.
