This low-profile rooftop AC keeps your RV cool in the heat and takes the edge off chilly mornings with built-in electric heat. Strong airflow, quieter low-speed operation, and a lightweight design make it an upgrade for real-world camping.

  • Strong Airflow, Quieter Nights: Two-motor system cools hard on high and runs quieter on low.

  • Works with Standard RV Power: Runs on 120V AC electrical systems.
  • Stays Looking Sharp: Textured black finish helps hide wear and resist fading.

Features to know about

How Does the Heat Pump Provide Heat?

The built-in heat pump reverses the refrigeration cycle to provide electric heat. It warms the coach without using propane, which helps on cool mornings and shoulder-season trips.

Why Choose the Mach 8 Plus Profile?

The ultra-low profile lowers wind resistance and keeps rooftop drag down while still delivering strong airflow. That means better fuel economy and less rooftop stress on long trips.

What Does the Two-Motor System Do?

Two motors let the unit push more air on high speed and run quietly on low speed. You get powerful cooling when you need it and a quiet cabin when you want to hear the radio or sleep.

Why the Fiberglass Basepan Matters

A fiberglass basepan keeps weight down without sacrificing strength, making the unit lighter on the roof and easier on the coach structure over time.

    Hey Christopher! A heat pump isn't available for the old Furrion you were referencing. Also, everything has moved from the old R410A refrigerant to R32 following the 2025 EPA regulations. Since parts aren't backwards compatible you will need a complete system replacement for your old Dometic setup. For an AC that comes with a heat pump I recommend one of the new GE Appliances AC systems. You can choose from the following: -GE Appliances Deluxe Plus RV AC System w/ Heat Pump - Ducted -...

  • Does 35004-0792 and 45004-0792 Coleman Mach 10 Have a Heat Pump?
    Hi Troy, I’m glad you reached out because there’s a bit of confusion around these model numbers and I want to make sure you get exactly what you’re expecting. The 35004-0792 and 45004-0792 Coleman Mach 10 you mentioned is a low profile 15,000 BTU unit with a built in heat pump, so you are looking at the correct version if heat pump capability is what you want. That said, we do not currently carry that exact Mach 10 model, and availability on those can be pretty limited depending on the...
