Grand Design has taken all of the best things about a luxury fifth wheel and combined them with the functionality of a toy hauler to create one incredible RV! The Momentum 399TH is jam-packed with amazing features like slam-latch baggage doors, frameless tinted windows, exterior security lights, and exterior entertainment center, and 2 power patio awnings with integrated LED lighting, plus a third awning over the garage.

Inside, the Momentum 399TH is full of luxurious amenities such as recessed LED ceiling lighting, blue LED accent lighting, the Espresso décor, and beautiful raised panel hardwood cabinet doors with hidden hinges. Cooking lunch or dinner will be a breeze in this exquisite kitchen. The solid surface countertops, 3-burner stainless steel stove top with oven below, a 30” stainless steel convection microwave, and the double bowl sink with sink covers built into the spacious kitchen island will ensure you have all the tools you need! But perhaps the best part of this kitchen in the 18 cu ft four door refrigerator that gives you all the space you need to ensure you have the ingredients you need for a hot and tasty meal!

Across from the kitchen, you’ll find a free standing dinette with chairs that invite you to take a seat and grab some dinner. Next to the dinette is theater style seating that make for a comfortable place to enjoy the LED HDTV located above the fireplace! The TV is mounted on a swivel arm so that you can view the TV from a convenient angle!

Also located in the main cabin is a twin-loft bed located above the garage that is accessible from the living room!

The best part about this model is the side porch! Just like the rear ramp, there is a side ramp that converts into a fenced porch. There are sliding doors in the living area that allow access. Out here you will also find another TV and outside entertainment area.

The 13’ garage is located at the back of the fifth wheel and provides plenty of space to not only bring along your favorite toys but also to accommodate more friends and family with the Happi-Jac electric bunk system with removable sofas. A half bathroom is attached to the garage with two entrances for the ease and convenience of everyone! This particular model also comes with the optional washer and dryer preps, garage screen wall and added patio seating!

Up the stairs, you will find a convenient side aisle bathroom with wonderful amenities like the porcelain toilet, the one-piece fiberglass shower with textured glass door, the freestanding decorative bowl sink, and the mirrored medicine cabinet.

The exquisite bedroom is located at the front of the fifth wheel and ensure you will rest easy in a true king-sized pillow top mattress below a residential style headboard. But that’s not all! You’ll also appreciate the generous amount of storage below the bed, wardrobes, and the large closet slide!

The Grand Design Momentum 399TH brings together style and fun! This beautiful fifth wheel can only fully be appreciated by stopping in to check out all of the unbelievable features!
