2026 Keystone Alpine 3712KB

This 2026 Keystone Alpine 3712KB is a luxury front living fifth wheel with a private bedroom, rear master bath, kitchen island, two pantries, and an 18 cu. ft. residential refrigerator. It is a strong fit for buyers who want a high-end fifth wheel with residential space, strong storage, and a layout built for extended trips or seasonal stays.

The front living area is one of the biggest advantages of this Alpine floorplan. Opposing tri-fold sleeper sofas help open up the room and provide extra sleeping space when guests come along. The front entertainment center, fireplace, 50 inch TV, and Thomas Payne theater seating give the living room a true residential feel for movie nights, relaxing, or spending time inside during cooler weather.

The kitchen is built for buyers who want more storage and better daily function. The island gives you extra prep space, while the two kitchen pantries, including a walk-in pantry, provide room for food, small appliances, and longer-stay supplies. The 18 cu. ft. residential refrigerator adds the cold storage needed for extended camping or seasonal use.

The private bedroom includes a king bed slide, giving the owners a comfortable place to sleep with more room to move around. Underbed storage adds another useful place for bedding, clothing, or personal items.

The rear master bathroom is another major feature on this floorplan. It includes a walk-in shower, dual sink vanity, washer/dryer prep, and a spacious layout that feels more like a residential bathroom than a standard RV bath.
