Question:
I currently have a 15,000 BTU DUI-THERM 59516.531 AC in a 2006 Travel Supreme RV. This is the origional AC. I need a replacement for it and i saw a video where an Advent AC replaced a Domentic AC and everyting plugged in with no problem They had to install a capacitor also. Is there an Advent system that will replace my AC and all the plugs match up? I am doing the work myself with the help of a friend.

Hey John, thanks for reaching out!
The Advent Air Low Profile RV Air Conditioner # ADV29FR that uses the R410a refrigerant might work since it has the 6-pin connector. You may need to move some of the pins around to make it work though - we've learned that it isn't always an exact fit from brand to brand.
The Advent AC # ADV86SR you referenced uses the new R32 refrigerant and if you wanted to go that route you'd need to install an entirely new AC System with the part # ADV92SR.
Which one are you leaning towards?

Hey John, did you decide to go with the Advent Air Low Profile AC or the new R32 system for your RV? I'm curious to know how it worked out for you, as it could help others in a similar situation.
