And Yes, TW = Tow Wehicle. LOL, sorry about that.
And it is a 2 way fridge and would be on propane.
Federal LAW requires a fully charged functional battery in trailer while towing to activate the Emergency Breakaway----required to maintain voltage/braking for 15 minutes should trailer become disconnected from tow vehicle.
Just saying....you will not be safely towing regardless of distance/time frame
As for fridge...
Tow vehicle '7 pin CHARGE' line is intended to charge/maintain trailer battery voltage while towing.
W/O trailer battery----fridge will not have DC for controls/gas valve because tow vehicle alternator/voltage regulator will not 'see' the fridge DC demand.
Buy a CHEAP 12V battery and toss it in the trailer........!~!
I find it hard to believe that the tow vehicle differentiates between the trailer battery and the truck battery. My guess is the two batteries wires are just tied together at some point and the computer sees the two as one big battery.
One easy way to find out. plug the 7 way umbilical into the truck and start the truck up. Then go into the trailer and see if the interior lights come on. If the lights come on then the refrigerator should work on gas.
