I have found you CANNOT use a "DIODE BASED" BATTERY ISOLATOR. Those high current diodes have a 0.7VDC voltage drop across them.

True, But (big but)many/most coaches with diode-based isolators use an alternator with external SENSE WIRE that is connected to the chassis battery terminal of the isolator. So the sense wire is reading post-isolator voltage.
Said another way, the alternator may be putting out 14.9 and the batteries ("downstream" of the diode-based isolator) receive 14.2.
