Four slides open up a floor plan that genuinely earns its square footage, a front bedroom with east/west bed orientation and a loft above, a second bedroom toward the rear, and two full baths including one with a dedicated entry door and bathtub. The kitchen is a real highlight: solid surface countertops, a stainless undermount sink, a center island, and a hidden pantry that keeps things tidy, plus a full outdoor kitchen when you want to move the party outside. A desk makes remote work practical, and washer/dryer prep means you can set it up for long hauls or full-timing without major retrofitting. Owners consistently call out the towing balance and storage as standouts, and Forest River has a reputation for working through any warranty issues that come up at delivery.
