Hey John, we can help but due to changes in AC refrigerant laws that went into effect in January of 2025 you would have to change all of the components of your AC setup as none of the current upper units can be controlled with the older style air boxes and controls.
So you'll have to go with an all new system which will include a new air box and thermostat to replace what you have. If you are wanting the best all around system the Furrion Variable Speed Chill Cube part # FR24TQ would be a really great option that comes with everything. This is the coldest blowing, the quietest, and lowest drawing unit around so you'll really like it.
