## Overview

A roomy garage gives the Keystone Carbon 338 plenty of flexibility for hauling gear, while the loft adds another sleeping area without crowding the front bedroom. Inside, Thomas Payne seating with heat, massage, and LED lighting faces a 50-inch TV and surround sound, with solid-surface kitchen counters and a 16.5-cubic-foot 12V refrigerator nearby. Two entry doors, outdoor entertainment, and the optional three-seasons patio door with patio awning make it easy to move between the living area and campsite.
