Pop up battery charging

Hi all,
We have a 2009 Rockwood Freedom 1970 , Will the battery charge when plugged into shore power or the tow vehicle?

Shorepower: Yes.

Tow vehicle: Yes (technically) but No (actually).

Any battery disconnect switch must be On to charge the battery.

Two issues with the tow vehicle. (1) Trailer battery charge line may not be active. Often requires a fuse or relay to be added to the vehicle and (2) even if active the tow vehicle's voltage regulator limits voltage to that necessary to recharge the starting battery. Will maintain the battery, and allow use of the 12v power setting on the little refrigerator.

Battery changes based on voltage differential and it's so very low via the tow vehicle that you'll have to drive for days to get the battery charged.

If you have a DC volt meter check voltage at the two battery terminals then hook up to the vehicle, start it up and check if voltage went up at the battery terminals. When plugging into shore power you will see a increase in voltage (maybe 1-1.5 volts). This way you know for sure.
