Other floor plans with a similar body style, feature mix, and price range, prioritizing other manufacturers and brands.
The 3990FL is built around a front living room that actually feels like one. Panoramic windows, a fireplace, and a 50" smart TV anchor the space, while the kitchen earns its keep with a farmhouse sink, solid surface countertops, a gas cooktop, and a proper island. A full loft with dedicated stairs adds real sleeping space without the awkwardness of a ladder, and the rear King bed comes with a walk-in shower and enough slide-out real estate to make the bedroom feel residential. Practical touches like an automatic leveling system, 200W roof solar, washer/dryer prep, and dual ducted air conditioners show this rig is set up for extended stays. Not just weekends.
