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?

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