2026 Keystone Alpine for Sale

The Alpine is Keystone's full-size luxury fifth wheel, sitting in the same premium tier as the Montana with its own roomy, well-finished layouts. It is built for couples and families who want residential-style fifth-wheel living, with big slide rooms, tall ceilings, large windows, residential kitchens, and front-living and rear-kitchen plans that emphasize entertaining space. Floor plans run roughly 38 to 43 feet on heavy tandem-axle frames, most with auto-leveling and solar prep. On RV Insider the Alpine averages 3.7 stars over about 91 reviews — slightly above the brand average — with owners praising the space and finish. As Keystone's lineup overlaps heavily at the top, the Alpine and Montana are natural cross-shops; the Alpine often comes down to which specific floor plan fits your needs and which you find at the right price. Like every luxury fifth wheel in this class it is heavy and component-laden, so a thorough inspection of the frame, slides, roof, and seals is essential on a used unit, and you will want a capable three-quarter- or one-ton truck to tow it.
