This is not entirely accurate. Many RV manufacturers continue to use "diode" based isolator, but yes, they do have a significant voltage drop. The "diode" style isolators are being obsoleted by MOSFET-based isolators where the MOSFETS (semiconductors) behave just like large, high current diodes, but have an insignificant voltage drop my magnitudes of efficiency and some high end motor coach manufactures are migrating to this never (sic) technology. There are several companies that offer MOSFET based isolator, but the best I could find was Perfect Switch in California. No affiliation but a super-please customer, FWIW
Would you care to name a few, or even ONE?
