2026 Freightliner Sprinter 3900DBL

The New 2026 Keystone Sprinter 3900DBL 5th Wheel is a spacious towable RV built for travelers who want the confidence and comfort of a dedicated fifth wheel. As part of the Keystone Sprinter lineup, the 3900DBL brings a proven model name to your camping plans with a clean, modern look and practical design.

As a fifth wheel, the 2026 Keystone Sprinter 3900DBL connects to a bed-mounted hitch for stable towing and composed handling on the highway. This setup helps keep weight centered over the truck bed for better control than a traditional bumper-pull. Bring a properly equipped pickup and verify your truck’s ratings match the manufacturer’s published specifications for this unit.

Inside, the Keystone Sprinter 3900DBL focuses on open living space and smart storage solutions that support weekends away or longer stays. The 5th Wheel layout separates the tow vehicle from the living area, creating a comfortable home base at the campsite with the familiar Sprinter feel.
