At just over 28 feet long with a single slide out to expand living space, the 257RB offers a roomy interior in a trailer that’s still manageable for many tow vehicles. Inside you’ll find a private front queen bedroom, a convertible dinette and sofa in the main living area, and a full kitchen equipped with a three‑burner range, microwave, refrigerator, and plenty of storage — ideal for cooking and camping with ease. The bathroom features a neo‑angle shower with skylight, foot‑flush toilet, and practical storage. Built with durable construction including a one-piece seamless roof, handcrafted cabinetry, high-performance vinyl flooring, and radius safety-glass windows, the 257RB is rugged enough for the road while staying comfortable for family trips or weekend getaways. Add a power awning, tankless water heater, ducted roof A/C, and a dependable gas furnace, and you have a travel trailer that balances practicality, comfort, and dependable build quality — perfect for families, couples, or anyone seeking a full-featured trailer without a bulky footprint.
