Millennium's signature build — a quad-slide, bath-and-a-half custom conversion on the flagship Prevost H3-45 shell.
The H3-45 is the heart of what Millennium does. The company takes Prevost's flagship 45-foot H3-45 shell — the high-floor touring-coach platform with the panoramic windshield — and hand-converts it into a custom residence on wheels. The builds Millennium showcases run a quad-slide, bath-and-a-half floor plan with exotic-wood cabinetry, fine leathers, and fully integrated power, climate, and entertainment systems, all on the proven Volvo D13 diesel and Allison automatic that underpin the Prevost chassis. Because every coach is one-off, there is no fixed spec sheet or MSRP: Millennium sells new custom H3-45 builds and a steady stream of pre-owned examples, nearly all listed call-for-price. For a buyer who wants the most coach Millennium builds on the most prestigious Prevost platform, the H3-45 is the default choice — just verify the specific build's systems and history before you commit.
