2018 388M Features and Options

Experience luxury, power, and versatility in one incredible fifth wheel with this Pre Owned 2018 Grand Design Momentum 388M. Built for adventure lovers who refuse to compromise on comfort, the Momentum 388M is a premier toy hauler designed to handle your gear while delivering a truly residential living experience wherever the road takes you.

Luxury Meets Rugged Performance

The 2018 Momentum 388M is known for its high-end construction and thoughtful design. Grand Design engineered this model with durability in mind, making it ideal for long trips, full-time RVing, or extended stays at your favorite destinations. From its solid build quality to its upscale interior finishes, this Momentum delivers both confidence and comfort.

Inside, you’ll find a spacious, well-appointed living area designed to relax and entertain. Large seating areas, premium materials, and smart storage solutions create a welcoming atmosphere after a long day of adventure. The garage space offers exceptional flexibility, easily transforming from a secure area for toys into extra living or sleeping space when needed.

The kitchen is designed for real cooking, not just quick meals, offering generous counter space, ample cabinetry, and residential-style appliances that make it easy to feel at home on the road. The master suite provides privacy and comfort, while the bathroom layout emphasizes convenience and livability.

Why the Grand Design Momentum 388M Stands Out

  • Proven Grand Design quality and craftsmanship

  • Versatile toy hauler garage for cargo, guests, or workspace

  • Spacious floorplan ideal for extended travel or full-time use

  • Residential comfort with high-end finishes throughout

  • Designed for stability, towing confidence, and long-term durability

Why Buy a Used Momentum?

Buying a used 2018 Momentum 388M allows you to enjoy a luxury toy hauler at exceptional value. You avoid the steep depreciation of a new RV while still getting a highly respected, well-built model that continues to perform year after year.
