Once at the RV park, unload your toys and set up the three slide outs, the two awnings, and begin planning your trail rides! You might decide to make a meal or snack in the combined kitchen and main living area which offers all the appliances you need, plus a kitchen island with two bar stools, a pantry, an LED TV with a fireplace below, plus a slide out four-seat sofa. The garage even offers the option to add two Happi-Jac rollover sofas with tables with a top bed if you want seating and sleeping space. The overhead loft bed provides sleeping space as well. You will love the sunken tub/shower with a seat in the full bathroom with a space savings sliding door, and the front bedroom can be your escape. There is a queen bed, a slide out wardrobe and USB charging outlets.

 

With any Momentum M-Class toy hauler by Grand Design, you will enjoy luxury at every turn! They have been constructed to a superior standard with a thermal roof design, triple insulated main floor and garage floor, and a Rail-Tite underbelly seal that will allow you to camp in all elements. Each model also features an 8' 5" wide body chassis with a wide rail design, no wheel wheels, and a dovetail entry for easier loading. The Stealth A/C system provides maximum cooling power, and the CRE3000 suspension system means you can enjoy a smooth tow each time. You will love the luxurious interior with a professional grade stainless steel cooktop, interior color changing LED accent lighting, a fiberglass shower with a glass door, and solid surface countertops.
