Available to Order

This 2026 Keystone Alpine 3910RK is available to order through Barton Lake RV. This unit is not currently on the lot and may be shown with stock photos. Availability, colors, equipment, and final pricing may vary, but this floorplan is a strong fit for buyers who want a luxury fifth wheel with a rear kitchen, bath and a half layout, dual entry doors, outdoor kitchen, and a true front master suite.

The rear kitchen is one of the biggest advantages of this Alpine floorplan. It gives you a dedicated cooking area with a large pantry, 18 cu. ft. residential refrigerator, solid surface countertops, and strong storage for longer stays. The rear entry door also gives you direct access into the kitchen, which is useful when loading groceries, bringing food in from outside, or using the camper at the campsite.

The middle living area uses opposing slides to open up the space around the free-standing dinette and two tri-fold sleeper sofas. That gives you a comfortable place to eat, relax, watch TV, or sleep overnight guests when needed. The fireplace adds a more residential feel and creates a comfortable focal point for the main living space.

The bath and a half layout is a major benefit, especially for guests or extended stays. The half bath is easy to access from the main entry and includes washer/dryer prep, giving the camper more long-stay convenience.

Up front, the master suite includes a king bed slide with underbed storage, a dresser, bench seating, and direct access to the full front bathroom. The master bath includes a dual sink vanity, shower with a seat, and private toilet area, giving owners a more residential setup than a standard fifth wheel bathroom.

Key features include a rear kitchen, bath and a half layout, dual entry doors, outdoor kitchen, king bed slide, underbed storage, front master suite, dual sink vanity, shower with a seat, private toilet area, washer/dryer prep, large pantry, 18 cu. ft. residential refrigerator, free-standing dinette, dual tri-fold sleeper sofas, fireplace, 100 inch wide-body construction, Tru-Fit slide construction, Blade Pure airflow system, day/night roller shades, solid wood cabinet doors, crown molding, solid surface kitchen countertops, outside shower with hot and cold water, Lippert strut-assisted SolidSteps, and large tinted safety glass windows.

For buyers looking for a luxury fifth wheel they can order with a residential rear kitchen, bath and a half convenience, and a private master suite, this 2026 Keystone Alpine 3910RK gives you the space, storage, and comfort needed for extended trips or seasonal camping.
