## Overview

The Grand Design Momentum M-Class 394M makes its garage especially useful, with rear cargo loading lights, a removable carpet kit, and a pull-down garage screen wall that lets the space shift between toy storage and living area. Inside, the residential-style kitchen pairs an 18-cubic-foot refrigerator with a 30-inch stainless microwave, while the sofa, removable swivel tables, fireplace, and color-changing accent lighting create a comfortable main living space. A one-piece fiberglass shower with glass door, skylight, porcelain toilet, and under-bed storage add thoughtful residential touches. Outside, dual power awnings, six-point hydraulic leveling, a patio setup, and blue under-unit lighting make the campsite just as functional.
