Question:

I’ve got a 07 forest river with a demotic a/c that wore out I’m looking for a13500 white advent a/c that will work with my demotic set up and wiring.

Hey Jason, we can help but we no longer recommend trying to fit an Advent AC upper unit to a Dometic lower unit. At one point we thought it was compatible but we found that only about 50 percent time it worked well. Plus they recently switched to a new refrigerant which means it definitely won't work.

So instead you'd want the part # ADV65SR which is a kit that includes all new components like you'd need. This will for sure work well for you.

Hey Jason, did the Advent Air Low Profile AC system work well with your setup? I'm curious to know how it turned out for you, as it might help others in a similar situation.
