My Frig isn't doing so well running on 12v when underway..... thought
in theory -  that you could run the frig while underway or parked for
1-2 hours....changng over to propane when stopped for longer periods or
for the night.....  new batteries and frig update  completed by
GoWesty.....talked with Chris at GW...he told me the aux battery
doesn't charge at the same rate as the main....I didn't know
this.....he suggested just staying on propane....btw:  frig works like
a champ on 110....

So....is the 12v frig feature a WASTE?  Is there anything that can be
done to resolve this?

Would installing a new alt help?

Thanks much
