Grand Design Momentum G-Class 394G Toy Hauler Travel Trailer — 2026 Model Overview

The Grand Design Momentum G-Class 394G is a premium towable RV designed for adventurous families and outdoor enthusiasts seeking a high-quality recreational vehicle with rugged capability and upscale comfort. This 2026 toy hauler travel trailer is new, built on a 101-inch wide-body super chassis, and combines a spacious interior with toy-hauler practicality, including a rear ramp door for easy loading of bikes, ATVs, or other gear. With three slides and a thoughtfully designed floor plan, it delivers ample living space without compromising payload or performance.

  • Residential-style amenities: fireplace, skylight, and insulate-for-year-round comfort

  • Comfortable climate: 15,000 BTU air conditioner and efficient electric heat and furnace options
  • Well-equipped kitchen: microwave, oven, and refrigerator for home-like convenience
  • Solar prep and modern power conversion for off-grid versatility
  • Robust construction and payload capacity to support active outdoor living

Interior Highlights

Inside, the Momentum G-Class offers a refined, family-friendly layout with smart storage, a cozy fireplace ambiance, and a dedicated space for entertainment and relaxation.

Why This RV Stands Out

As a Grand Design vehicle, the Momentum G-Class 394G pairs rugged mechanical capability with modern comfort, making it a strong choice for travel trailer enthusiasts who value reliability, resale value, and a well-thought-out floor plan. Whether you’re chasing mountain trails or coastal campsites, this towable toy hauler delivers the versatility, comfort, and convenience needed for unforgettable road adventures in an RV, a true recreational vehicle for families and explorers alike.
