2017 Grand Design Solitude 310 GK
Features and Enhancements
This 2017 Solitude 310GK by Grand Design has been significantly enhanced and very well maintained and it is immediately ready for use. There are blankets on the bed a goose down comforter in the closet, dishes and glassware in the kitchen cabinet, flatware in the drawer and even a coffee pot included. Every Solitude fifth wheel by Grand Design is built with luxurious finishes and ultimate convenience for extended stays or short getaways in any weather but this one is actually better than new. (Please see Highlights and the included complete feature list).
Grand Design (GD) was founded in 2012 with a strong focus on providing luxury, quality and convenience at an affordable price. GD was acquired by Winnebago in Nov. 2016. Six months later there was a mandate to dramatically increase production while restricting manpower expansion. There was a potential risk of quality degradation. This unit was built prior to that mandate.
This 310GK was built with a solid foundation on an exclusive super chassis with options that include maximum insulation and multiple heat sources.
The kitchen features a professional-grade tempered glass covered steel cooktop with built-in oven, a convection microwave and a full height lighted pantry with a glass and wood panel door. The chef can prepare meals on the kitchen island and there is plentiful additional counter space. And there is a stainless steel 18 cu. ft. four-door refrigerator/freezer that runs on gas or electric.
NOTE: Manufacturer’s Suggested Retail Price for a new Solitude 310GK with no options or enhancements is $147,540. This one, fully updated and well maintained with all options will cost far less than half of that. Please see feature list and photos. (Additional photos available.)
