Can An AC Unit Be Installed In Place Of A Roof Vent?

Question:

I’m wanting to put this on my keystone Montana 3791rd. Could I place this in the kitchen area where the vent fan in the roof is.

Hello Kolton, thanks for reaching out. The Furrion Chill Cube RV Air Conditioner # FR59TD does install into a standard 14"x14" roof opening. Most roof vents use this same opening size, so it would be possible to install an AC unit in its place.

The # FR59TD is a complete AC system so it does come with everything you need to add an AC system to a ductless camper. You get your rooftop unit, distribution box and thermostat/controller.

I have included a link to our video that shows and example of installation.

Hey Kolton, did you get a chance to install the Furrion Chill Cube AC in your Keystone Montana's kitchen area? I'd love to hear how it worked out for you, as it could help others looking to do the same.
