Some late model high capacity refers have a horizontal mounted compressor motor and as the coach brakes allows the oil and refrigerant to slosh around and run oil into the compressor motor it was not designed to have in it.
My guru buddy mentioned hearing the pump in the house refers trying to compress the oil and hearing the pump chatter.
Refer was not designed to be in a moving vechile. He said the older refers had a more conventional mounted compressor versus a laid down design that is mounted right to left. Which is front to back mounted sideways in a coach.
Average use age reported seems to be 100 amp hours minimum per day to run a household refer.
As My normal overnight aqua hot and lights seem to average around 150 amp hours dry camped so adding an additional 100 would total 250 amp hours out of 675 I have.
That perecentage discharge done daily will shorten my battery life by a large fraction.
Large solar on roof or having a pedestal to plug in nightly makes the residential refer an easy install.
We prefer quiet dry camping so the additional gen run time is something we do not want.
As sort of preppers the additional gen run time greatly shortens our time on internal fuel only.
