Our coaches pre-date reliable transfer switches, so they were all built with the APU outlet in the cable bay. We leave them plugged in always.

To unload the APU (genset) for starting, just don't turn anything on. Even my 40+yo Onan 4K will run up with the load of the converter and the waterheater (maybe - it is not always on). If we are underway and want the roof air or the microwave, we just fire the APU and wait the 30~45 seconds until it is stable.
