2017 399TH Features and Options
You can pack a whole lot of fun into this Momentum toy hauler fifth wheel by Grand Design!  Model 399TH offers a 13' garage for the toys, plenty of sleeping space for a few extra buddies to tag along, and kitchen and bath amenities like home. Check it out....one and a half baths, a fireplace, an 18 cu. ft. refrigerator, and a fold down side patio, plus so much more!  How's that for living on the edge....of fun that is!

With 13' of toy parking space you can take it all.  The rear ramp door will make loading and unloading a snap.  Inside the garage area you will find an LED TV, overhead cabinets in the corner, an overhead loft near the front of the garage, and a half bath so you can easily keep all the dirt and grim out of the main living space.  You can even add an optional Happi-Jac with rollover sofas including a top bed for added seating and sleeping space once the toys are removed. In the cargo area there is a side man entry door for quick access to the garage and half bath, plus a rear patio and just off the garage you have access to a fold-down side patio to enjoy a little down time outdoors.

On the inside of this cool toy hauler you will find a home like space filled with everything you need to relax and refuel for another day of fun.  There are dual opposing slides in the main living room and kitchen area.  An 18 cu. ft. refrigerator will keep all of your cold stuff cold, and there is a three burner range and overhead microwave oven for all of your cooking needs.  These are both found in a slide out along the curb side.  A center island features a double sink, plus added counter-top prep space.

Opposite along the road side another slide with a free standing dinette and theater seating for two.  You can opt. for a super sofa instead.  An entertainment center with a LED TV and fireplace below are along the angled outer bathroom wall and easily viewable from the seating in the room.

Head up the steps to a front master bedroom and complete bath. The bath is found on the right at the top of the steps up and includes a large shower with skylight and seat, linen cabinet, toilet, and vanity with vessel bowl sink. A second bath entry door slides to allow easy access right into the front master.

In the bedroom you can easily rest and enjoy a little down time. There is a comfortable queen or optional king size bed, dual nightstands, overhead cabinets, and a slide out closet for all of your clothing storage.

You will appreciate the convenience of the unobstructed pass-thru storage compartment when loading and unloading your outdoor gear, plus the universal docking station, and more!

ManuFacts
Grand Design Recreational Vehicles is a superior quality manufacturer of towable fifth wheel and travel trailer RV's. Based in Middlebury, IN, Grand Design RV focuses on providing the highest quality and more premium standard features than any other RV's in their class.

Founded by close friends Don Clark and brothers Ron and Bill Fenech (each having over 25 years of experience in the RV industry).  Although they have lead some of the most successful companies in the RV industry, and are proud of their accomplishments at Keystone RV, they recognized that it was becoming more difficult to stay in touch with the needs of customers, employees, and the products being built. 

So, in 2011 they began pursuing their dream of reconnecting on a more personal level with customers and dealers.  The result of that pursuit is Grand Design RV.  A company designed to create recreational vehicles that provide more features, better designs and unparalleled customer support!
