Hello Angel, thanks for reaching out. We can definitely provide a replacement rooftop AC unit for your 2018 heartland Bighorn. The # FR42PV is an older part that has been discontinued though. When manufacturers transitioned to the newer R32 refrigerant systems, that model was phased out, which is why you are not seeing it available anymore.
For your 2018 Heartland Bighorn with a 15K BTU ducted system, you can absolutely replace the rooftop unit, but the newer systems will require replacing the rooftop unit, air distribution box, and thermostat as a matched system. The best all in one option I recommend is the Furrion Chill Cube # FR69TD. This kit includes everything needed for the upgrade and is designed to work with ducted setups.
The Chill Cube units are a great upgrade over older AC systems. They run quieter, cool more efficiently, and offer improved performance in high heat.
