Description

Grand Design Reflection fifth wheel 337RLS highlights:

Rear Tri-Fold Sofa
Fireplace
Hutch
Theater Seating
Solar Package

You can enjoy a spacious rear living area in this RV with dual opposing slides offering you entertainment, kitchen amenities, seating and windows for great views! The rear tri-fold sofa also converts into extra sleeping space for an extra guest or two, just like the booth dinette does. Yet you might like to add the swivel dinette option. There are theater seats to enjoy while you place your drinks in the cupholders and watch the entertainment center with a 40" LED HDTV and fireplace. The pantry is big enough to store your favorite snacks, and the kitchen island will make meal prepping easier, plus there is a 16 cu. ft. refrigerator to store any leftovers. The full bathroom has a 30" x 48" fiberglass shower and a linen closet to store your towels. The front private bedroom has a comfortable queen bed slide that can be switched out for the optional king bed, a dresser with overhead cabinets, and a full wall wardrobe that is prepped to add the optional washer and dryer so that you can extend your camping trip with clean clothes!

With any Reflection fifth wheel by Grand Design, you will have a solar panel for off-grid camping and a 60 amp charge controller and inverter prep, a Universal All-In-One docking station, unobstructed pass-through storage, and Goodyear Endurance tires. Each is constructed of gel coat exterior sidewalls, residential 5" truss rafters, walk-on roof decking, a fiberglass and radiant foil roof and front cap insulation plus laminated aluminum framed side walls, roof and end walls in slide rooms. Head inside to enjoy residential hardwood cabinet doors, premium Congoleum flooring, a spacious shower with a glass door, and many more comforts!
