The cook can prepare the meals on the kitchen island and store leftovers in the stainless steel 18 cu. ft. four-door refrigerator. When you and your spouse aren't outside, the big screen LED TV in the living area can keep you entertained while staying warm by the fireplace. There is plenty of storage throughout for your shoes, dry goods, linens, and your wardrobe. You might even like to choose a few options such as adding a washer and dryer, a dishwasher, a king-size bed, or even a pull-out kitchen outside. Come see how this Solitude will make life comfortable for years to come!

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.
