NEW 2026 Grand Design Solitude Fifth Wheel 390RK

Experience true residential luxury on the road with the New 2026 Grand Design Solitude 390RK, a fifth wheel built for extended stays, seasonal camping, and full-time RV living. With five slides, a raised rear kitchen, and expansive living space, this Solitude delivers comfort, functionality, and upscale design in every detail.

The raised rear kitchen is a standout feature, giving you a chef-inspired workspace with stainless steel appliances, a built-in oven, solid-surface countertops, and an oversized pantry for long trips. A bar-top counter with chairs adds extra prep space while creating the perfect spot to dine, work, or entertain, all while overlooking the spacious middle living area.

In the main living space, relaxation comes easy. Dual tri-fold sofas and plush theater seating provide plenty of room for guests or quiet evenings in, while the LED Smart TV and fireplace create a cozy, residential atmosphere you’ll appreciate after a long day of travel or exploration.

When it’s time to unwind, the private front bedroom offers a queen bed slide-out for added floor space, a slide-top dresser, and a large front closet with washer and dryer prep, making extended stays simple and comfortable. The spacious bathroom features a dual-sink vanity, allowing two people to get ready at once with ease.

Outside, practical storage solutions like the exterior sliding tray make packing and accessing your gear effortless, whether you’re staying for a weekend or several months.

Built with Grand Design’s premium construction standards, the Solitude 390RK is designed for year-round comfort and long-term reliability. The Weather-Tek Package, heavy-duty 8,000 lb. axles, MORryde suspension components, and 101" wide-body construction ensure this fifth wheel is as capable as it is comfortable.

Pleasant Experience!

Meet the owner in Buffalo and talked to him and gave him a pair of gloves to dump his RV, what a pleasant guy to visit with. I would go in when I’m ready to buy. - Sheldon
