You can say it until the cows come home. You don't know how much charge is left in the battery at the end of a 10-12 hour travel day, especially in my rig that operates a residential fridge off an inverter while we're traveling. You think I should disconnect MY trailer batteries from the tow vehicle? SMH.

Any trailer with a residential refer should have a dedicated 12v system isolated from the primary battery or a shutoff circuit to prevent draining the primary battery. Otherwise it is a bigger safety risk than anything else mentioned. For units with an Rv refer, converter output is much higher than normal load and a good battery should be fully charged when leaving a CG. If someone is towing with a defective battery then a 12v feed from the tow vehicle will not make the rig safe.
