New 2026 Forest River SANDPIPER 3900HBLR

Floor Plan

he 2026 Sandpiper 3900HBLR brings a thoughtful triple-slide layout, solid construction, and convenient amenities built for campground comfort. With three slide-outs and a king-bed slide, this fifth wheel offers roomy, flexible living space that adapts to travel or extended stays. 

Walk in and you’ll enjoy an open rear living area with an L-shaped sofa with chaise lounge and an entertainment center — a cozy spot for relaxation after a day outdoors. A hidden butler pantry and a large kitchen island make mealtime easy. 

The kitchen includes a 16 cu. ft. 12-V refrigerator, stainless-steel appliances, and deep counters, giving campers real cooking and storage space. 

In the bedroom you get the king-bed slide, ample storage, and washer and dryer installed, adding a home-like convenience that’s hard to beat on the road. 

The bathroom is well-equipped with a walk-in shower, and there’s a bath-and-a-half layout for extra flexibility.

Built tough, the 3900HBLR rides on 7,000-lb axles with anti-lock brakes, includes an automatic electric level-up system, and offers pass-through storage for gear or supplies — practical extras that make a real difference for campground trips. 

If you’re a camper looking for a fifth wheel that balances space, features, and comfort — the Sandpiper 3900HBLR is worth a close look.

Available now at Tri-Am RV Center.
