Hey Junior,

With the new year came new changes to our AC units. We no longer have units that are compatible with other brand units. For your Dometic Duotherm, since we do not carry those units I recommend a new system like the Advent Air # ADV95SR 13,500 btu system. This comes with everything needed to install included the distribution box and wall thermostat.

If you wanted to stick with Duotherm you would need to reach out to Dometic directly to see if they can get you that exact unit to replace. Otherwise a new system is your best bet.

What kind of trailer do you have that unit on?

It is on a 2002 Coachman Aurora motorhome

@Junior Great motorhome right there. Advent does make a low profile that sits 10-1/8" tall so it is going to be almost the same size as your current unit. The same system but low profile is going to be # ADV65SR.

Hi Nick, Is this the only unit that will replace the 600315.321 or do you offer any others in stock?

@Jeremy We do have some other options. Since you will need to replace the system anything is going to work. The Advent is a great quality AC but we also carry a Furrion system # FR52TD as well as a GE Appliances AC # GE52ZR.
