Description
Grand Design Solitude fifth wheel 378MBS highlights:
- Middle Bunkhouse/Office
- Kitchen Island
- Four-Door Refrigerator
- Free Standing Dinette
- Outside Beverage Cooler & Grill
- Two Power Awnings
Looking for an extra room to utilize many ways in your next extended stay RV? Well you have found it in this middle bunkhouse with a fold down bunk above a tri-fold sofa that offers seating for an extra living room as well as sleeping space for a bedroom, plus there is a desk to work from and a closet for clothing and supplies making this room multi-functional. You can then retreat to your own master bedroom with a queen bed slide or choose the king option, a pull-out ottoman giving you a place to sit while taking off your shoes, an LED TV as well as a space prepped for a washer/dryer option. The main living and kitchen area is spacious with dual opposing slides and offers theatre seating and a tri-fold sofa to relax on while watching the LED Smart TV and visiting with the cook in the kitchen that offers a kitchen island, a 24" residential oven, and an oversized pantry to store lots of dry goods and snacks. You will surely enjoy the two power awnings and the outside grill plus beverage cooler while relaxing outdoors.
With any Solitude fifth wheel by Grand Design, you will get maximum insulation from the thermal roof design, the exclusive fully laminated walls, the triple insulated main floor, the Rail-Tite underbelly seal, the insulated gooseneck and the insulated baggage doors. The MORryde rubber pin box system utilizes a unique rubber shear spring to positively deal with rough towing and road shock, the Tire Linc TPMS system monitors pressure and temperature, and the 6-point hydraulic system allows you to setup easily. And the upgraded shower system, the hardwood window valances, the oversized kitchen pantry, the window above the master bed headboard, and the Rockford Fosgate stereo entertainment system with HDMI and App controls are a few more reasons you will love these extended-stay fifth wheels!
