Prevost's raised-floor flagship shell — the chassis under most of the world's finest conversions.
The H3-45 is the platform you picture when you hear the words 'Prevost conversion.' It is Prevost's raised-floor flagship: a 45-foot, three-axle stainless-steel monocoque shell with a Volvo D13 diesel, an Allison automatic, and a high, commanding driving position over a cavernous luggage bay. That raised floor is the whole point — it lifts the living space up over enormous basement storage and gives converters a tall, flat, generous canvas to work with, which is exactly why Marathon, Liberty, Featherlite, Emerald, and Millennium build most of their top coaches on it. Be clear about what you are buying: Prevost builds this shell to the same spec for everyone, so the bus underneath is world-class and built to run well past a million miles. The interior, the slide count, the price, and the quality are entirely the converter's doing. Judge the conversion, not just the badge.

What buyers love and what to watch
What buyers love
- The most sought-after Prevost platform — the shell under most flagship luxury conversions.
- Raised floor means a commanding drive and an enormous basement few coaches can match.
- World-class chassis durability; a clean used H3-45 conversion is a lot of coach per dollar.
What to watch
- Interior quality, layout, and price are the converter's work — not Prevost's. Vet the builder.
- A 45-foot bus needs commercial diesel/air-brake service and a budget to match.
- Older shells can develop costly sidewall delamination — inspect any used coach hard.
Notable features
- Raised-floor design with up to ~460 cu ft of pass-through basement storage
- Volvo D13 diesel with Allison automatic — built for million-mile commercial-grade duty
- Stainless-steel monocoque body and air-ride suspension for the brand's signature quiet, smooth ride
- Tall, flat conversion canvas favored by every major luxury converter
