Since the Airxcel is a Coleman unit the Furrion Chill HE part # FR62PV would be a really great option and my first recommendation. This is designed to fit in place of the Coleman units so it would install easily. It's also the quietest and coldest blowing unit we have so it would work great as well.

Advent air does also make a unit that was designed to replace Coleman units with the part # ACCOL150 which comes with wiring that allows it to plug right in as well.

Hi there! I also have the Airxcel 48254A866 - and as the individual above said this is a 15,000 BTU unit. I’m curious why you recommended replacing that with a 13,500 BTU unit? Mine is 12 years old and finally kicked the bucket a couple months ago. I have a separate furnace in my system. I saw some other questions on the forum that were talking about adding a heat strip to the roof mounted AC unit (if replacing with Furrion). Would I need to add that also, or not? (because I have a gas furnace in my system.) Or would it be best just to go with the current Coleman?

@PhilS Hey Phil so this is all basically outdated info in this answer page now as we have learned that all of the units we offer that are designed to replace other brands don't work very consistently. But to answer your other question if you have a furnace I wouldn't mess with a heat strip as that won't really affect much and you already have an actual heater. You'll need to replace the entire assembly which for that the best option is the Furrion Chill the cube part # FR69TD. This comes with absolutely everything including a thermostat, lower vent assembly, and a remote that you can use as a remote thermostat sensor.
