If you have time and know an answer please let me know. I'll be checking back in the morning. Thanks!
Other members will likely have better input as to running the propane while underway.
From your trailer connection description it sounds like you are adapting to a 4 wire in-line connector. That would mean that while towing you don't have electric brake capability or "charge" as you mentioned.
I doubt that your trailer refrigerator has a standing pilot (although it could have a replacement unit of some sort) so even when you are cooling with propane you still need 12 VDC for the refrigeration controls. Without the "charge" from your vehicle you will be depending completely on your TT battery for 12 volt supply unless your are connected to 120 volt AC shore power or running a generator (I know, highly unlikely).
If your TT battery is good condition and fully charged it should power the refrigeration for a day of travel with no problem. If the battery is old and on its way out... who knows??
Sorry I can't offer more. vic
