Hello Joshua,
Thanks for writing in!
Since you used the word best, let me introduce you to the Furrion Chill Cube Variable Speed RV AC System with ADB & Remote - 18K Btu - Non-Ducted - White - R32 # FR59TD. If your RV has a ducted setup, the equivalent system is # FR99TD.
The feedback I've received from neighbors (customers) has been amazing. I even had one neighbor tell me that after installing the Chill Cube in the front of his RV, he no longer needed to run his second AC to keep the coach comfortable. That's the kind of real-world feedback that gives me confidence recommending it.
The system comes with the rooftop AC, the air distribution box (or ducted ceiling assembly on the ducted version), a remote control, and the mounting hardware needed for installation. One of the biggest advantages is the variable-speed compressor. Instead of constantly cycling on and off like a traditional RV air conditioner, it adjusts its output to maintain the temperature you set. That means it's noticeably quieter, keeps the temperature more consistent, and doesn't have the large startup power draw of a conventional AC.
As for your furnace, I actually recommend keeping your current thermostat for furnace operation. The Chill Cube uses its own controls and remote for the air conditioner, while your existing thermostat continues to operate the furnace.
If your goal is to reuse your existing wiring, control box, or a heat strip that's installed in your current air conditioner, the Chill Cube would not be the best choice. Beginning in 2025, the RV industry transitioned from R410A refrigerant to the newer R32 refrigerant. Because of that change, the components are not compatible, so the rooftop unit, controls, and ceiling assembly are designed to be replaced together. While it isn't a plug-and-play replacement, it gives you an entirely new, modern system with the performance improvements I mentioned above.
If your priority is keeping costs down while still getting a dependable replacement, I'd recommend the Advent Air RV AC System with Wall Thermostat - 15,000 Btu - Ducted/Non-Ducted - White - R32 # ADV92SR. It also comes as a complete system because of the R32 refrigerant change, but it includes a wall thermostat that can control both the air conditioner and your furnace, making it a great option if you'd rather have everything operated from one thermostat instead of using a separate remote for the AC.
Do you ever use your heater when you are camping, or are you more of a summer camper needing to stay cool?
