Emerald's sleek, modern Prevost "touring bus" conversion — the technology and storage flagship.
The H3-45 is Emerald's conversion of Prevost's modern "touring bus" shell, and it is the one most buyers picture when they think of a current Emerald. At a full 45 feet on a shorter 313.4-inch wheelbase, it delivers the most underfloor storage in the lineup — 505 cubic feet — along with the higher profile and panoramic windows the H3-45 platform is known for. Power is the legendary Volvo D13 diesel, rated up to 500 horsepower, through an Allison 6-speed automatic. What sets the H3-45 apart inside is the technology: a 58-volt Volta lithium house-power system that cuts hundreds of pounds versus a conventional bank, a Crestron control system designed to be simple to run, and oversized HD TVs including a 65-inch screen in the lower-bay entertainment center. Emerald offers it in one-to-four-slide configurations and pitches it as a value leader against far pricier Prevost conversions. The honest caution: this is a hand-built, million-dollar-plus coach with specialized service needs, and detailed cabin specs vary because every unit is essentially custom.

What buyers love and what to watch
What buyers love
- The most underfloor storage in the lineup (505 cu. ft.) and the platform's panoramic-window cabin.
- Genuinely advanced, well-integrated tech — Volta lithium power, Crestron control, big screens.
- Pitched as a Prevost "value leader," priced below the average conversion in its class.
What to watch
- A hand-built, million-dollar-plus motorcoach — values around $1.5M–$1.7M used, not a mainstream RV price.
- Every unit is essentially custom, so sleeping, bath, and material specs vary build to build — inspect the exact coach.
- Prevost shell plus Volvo D13 and integrated systems need specialized service, not a corner RV shop.
Notable features
- 58-volt Volta lithium-ion house-power system that cuts hundreds of pounds versus a conventional bank
- Crestron-based control system designed to be simple to operate, with smartphone/tablet/smart-TV control
- Oversized HD LED TVs — 49-inch in living room and bedroom, 65-inch in the lower-bay entertainment center
