    AI summary

    The Riverstone Reserve 3950FWK puts the kitchen front and center, literally, with a sprawling layout anchored by an 18 cu. ft. French door refrigerator with ice maker, upgraded Calcutta solid surface countertops, a Fisher & Paykel dishwasher, and a 3.7 cu. ft. oven with a four-burner range. Bar-style seating keeps the space social while a built-in desk on the sofa/desk slide gives full-timers a dedicated workspace without sacrificing the open feel. The living room fireplace, central vacuum, Truma on-demand hot water, and stackable washer and dryer round out the residential experience, and the bedroom lands a 10-inch memory foam mattress on a King bed with under-bed storage. Worth knowing: the bedroom slide needs to be out to walk through, so this one rewards campsite living over frequent moves.
