Your Dometic 57915.531 is a 13.5k BTU AC unit which the Advent Air RV AC Unit # ACDOM135 is the same size and is also designed to replace Dometic units.

@Mike Are you looking for an all new unit with a new lower vent assembly too or something that would just replace the upper unit of what you have? What is it that you have by the way?

Hello, I am also looking to replace just the upper unit, Duo-therm 57915.531. What are my options?

@David If you want to only replace the upper unit you'd have to go with a Dometic Duo Therm like you have now as there's no way to mix and match brands between upper and lower units.
