Coleman 38204-0645 Mach 15 Roughneck 15,000 BTU Rooftop RV Air Conditioner with Wiring Box

The Coleman-Mach 38204-0645 Mach 15 Roughneck is a 15,000 BTU rooftop RV air conditioner engineered for demanding environments. Part of the rugged Roughneck Series, this unit features fortified interior construction designed to withstand the jarring, vibrations, and harsh conditions of off-road travel, construction sites, oil fields, and heavy industrial vehicle applications. This package includes an integrated wiring box for simplified electrical connection during installation.

At the top of the Coleman-Mach lineup, the Mach 15 delivers the highest cooling output in the Mach Series, backed by a 1/3 horsepower fan motor — the largest used in any RV air conditioner — pushing cool air at an impressive 320 CFM. That airflow capacity makes it an ideal choice for ducted systems. The unit operates on 115V AC / 60 Hz power, draws 14.2 amps at high cool, and runs at 1,611 watts. It uses eco-friendly R-32 refrigerant.
