## Overview

Storage is a genuine strength here — the XL pass-through compartment with entertainment hook-up is unusually generous, and oversized baggage doors with a fold-down bike/storage rack round out an exterior built for real trips. Inside, the kitchen punches above its class with solid surface countertops, hand-glazed hardwood cabinet doors, a deep stainless steel basin with sink cover, and a full-extension pots-and-pans drawer. The residential shower/tub surround, Cougar Platinum orthopedic mattress, and a fireplace (standard on this model) make the living spaces feel more like a cabin than a trailer. Four-point auto electric leveling, a fully heated and enclosed underbelly rated to zero degrees, and the Cougar camp remote mean setup and shoulder-season camping are far less of a chore than on comparable units.
