The Forest River Sierra Destination 399LOFT is built around the idea of staying put, with a rear bedroom, a front living area, and a loft that adds real sleeping capacity without eating into the main living space. The kitchen island anchors a well-equipped cooking area with solid surface countertops, a stainless undermount sink, a Chef Collection 3-burner range, and a 19 cu. ft. 12V stainless refrigerator. Two entry doors make daily living more practical, and the dual ducted 15,000 BTU air conditioners keep things comfortable, with the unit already prepped for a third. A 60,000 BTU on-demand tankless water heater and a fiberglass one-piece shower with a folding teak seat round out the amenities for extended stays.
