I plug my Progressive EMS into the 30A out on a pedestal and then plug my trailer cord into it. I have never worried about installation. I had a previous Progressive EMS (same one as I have now) fail while camping and they promptly replaced it. I did pull it out of service at the campground and went without till we got back home and my new unit was waiting for us and has functioned fine since. The Progressive EMS was once USA made and is now made in the 3rd world. Are failures more likely? Dunno. You can root around behind your converter and use your bluetooth gizmos but I like to be able to put my EMS in place and remove when we leave a campground.
