## Overview

A roomy rear garage gives the Keystone Carbon 340 substantial space for hauling toys, while the front bedroom keeps the 76-by-68-inch King bed separated from the main living area. Inside, soft-close cabinetry, solid-surface countertops, a farmhouse sink, a 16.5-cubic-foot 12V refrigerator, and a 50-inch TV create a residential feel. The full bath, 188-gallon fresh-water tank, six-point hydraulic auto-leveling, and optional three-seasons patio package add comfort and flexibility at camp.
