  • Bunkhouse/Office
  • Loft
  • Kitchen Island
  • Four-Door Refrigerator
  • Oversized Pantry

You could be working steps away from the best views of the mountains in this Solitude fifth wheel! Imagine having a bunkhouse that includes a sofa and a desk for your multi-purpose room. You will find a loft above for extra sleeping space or storage, a full bathroom, and a master bedroom with everything you need! The kitchen includes aprofessional-grade stainless steel cooktop, built-in oven, microwave, a stainless steel 18 cu. ft. four-door refrigerator, plus a large pantry. You will also love the center island and hutch for additional space for your things.

With each Solitude fifth wheel by Grand Design, you will receive refined residential finishes and affordable luxury for your extended stays or weekend getaways. From the solid foundation that rests upon an exclusive superchassis and the maximum insulation to the taller ceilings, taller and deeper cabinets, and the power reclining theatre seating with removable swivel tables and heat and massage, you will be impressed! The pet dish drawer, the Stealth AC system, and the Weather-Tek package that allows you to travel during any season will also give you many more reasons to love everything about your Solitude. It's time to redefine luxury living wherever you decide to land.
