Question:
Hello. I just wanted to get some confirmation on this unit. I have a 2020 Grand Design Reflection fifth wheel 28 BH. It has a Coleman-Mach model number 48254c869. Is the Advent Air ACCOL150B a direct replacement? Thank you for your help.

Hey Carl, thanks for reaching out!
Yes, the Advent Air Replacement RV Air Conditioner for Coleman Setup # ACCOL150B will work as a replacement for your Coleman-Mach 48254C869 air conditioner.
Are you planning on installing this yourself, or are you wanting to have a shop install it for you?

Hey Carl, did you decide to install the Advent Air replacement yourself, or did you have a shop do it for you? I'm curious to know how it went, as it could help others considering a similar upgrade.
