Will fridge run off tow vehicle on batts on TT?

Simple question, but I cannot seem to find an answer. Every search results in "will my TV charge the batteries".

Normally wouldn't care, but here's the scenario. Just got a new to me TT but I plan to keep the 2x 6volt batteries from my old trailer. To make them fit I need to make some modifications but its going on a trip before I will do that.

So, will the fridge stay powered by the TV on until I get to the site where I can throw the 2 golf cart batteries on the tongue temporarily?

There will be no battery, it needs to go in the Nash that I am selling.

And Yes, TW = Tow Wehicle. LOL, sorry about that.

And it is a 2 way fridge and would be on propane.

The 7-pin will help while your fridge is on propane, but not do enough while the fridge is on 12v if it is a 3-way fridge.

If the fridge is cold already before leaving it will stay cold that day till you get there if you leave the doors closed.

You need a battery in the TT to tow it (it's the law) so the emergency breakaway will work.

With the required 12v battery and the 7-pin, now you can use the 12v mode on the 3-way fridge and it will help keep it colder than without.

Hard to say.. I'd be using a voltmeter to find out. We're all assuming you mean it's running on propane, and that TW means TV.

Will there be any battery in the trailer? On propane, they take very little 12 VDC power.
