Here is my .02 on the domestic situation based on my experience with them. One, Newell used twist on connectors in the silver control box to tie to house power. They loosen over time and heat up. They should be checked yearly. Two, the relays on the control boards that power the compressor and condenser fan can fail. They are easily obtained and replaced with basic soldering iron skills. Three, the condenser fAn motors eventually fails because it is an oilite bronze bearing. The bearing wears to the points it makes the motor hard to turn. Newell has always been able to supply me with spares. I actually think they were having someone make them in batches for them but don't trust me on that statement. Four, properly gassed and clean the domestic units will turn the coach into Antartica if you let Rhonda control the thermostat.
