Recent builds, probably newer than a 2015, have a different A/C unit and there is a Technical Service Bulletin relating to installation.
On earlier Dometic A/C units, including the ones likely in your 2015, there have been a number of failures related to Dometic moving manufacturing to China.
You might want to call Dometic to see if they have established any special programs to deal with the manufacturing issue. But if your current unit is working, they may tell you that it'll be ok.
