RV Rooftop A/C Replacement for Coleman Model 47074A879
Products Featured in This Question
Question:
I have a 2015 Tiffin Allegro RED, Model 33AA. One of the rooftop air conditioners/heat pumps failed and needs replacement. That unit is a Coleman Model 47074A879, 13,500 Btu, low profile. Would like to upgrade to a 15,000 Btu unit. Even though its high profile, could the Atwood be a direct replacement for the Coleman? Or, do you have any other suggestions? Thanks for your help.

I do have an option for you but the Atwood Air Command Rooftop RV Air Conditioner w/ Heat Pump - 15,000 Btu # AT15033-22 is not a direct replacement for your Coleman 470704A879. We have the Advent Air RV Air Conditioner - 15,000 Btu # ACM150 which the manufacturer list as a replacement for the Coleman Mach Units using the Coleman Mach Adapter Wiring Kit for Advent Air # ACCOLKIT. This adapter allows an Advent Air AC to work with your existing Coleman Mach setup.
This A/C does not come with the heat pump so you would want to look into the Electric Heat Strip for Advent Air RV Air Conditioners # ACMHD to remove the chill from your RV or camper on cold or frosty mornings.
This unit is also available in black. Advent Air RV Air Conditioner - 15,000 Btu - Black # ACM150B.
