The 2026 Alliance Paradigm 388SP redefines the fifth-wheel experience by utilizing a 101-inch wide-body chassis, creating an interior that feels significantly larger and more open than standard models. This "Benchmark" chassis supports a layout designed for extended living, featuring flush-floor slides that eliminate carpet and tripping hazards, and Azdel composite sidewalls that provide superior insulation against the elements. You will appreciate the residential climate control provided by three high-efficiency air conditioners, ensuring that every corner of this spacious rig stays crisp and comfortable regardless of the forecast.
