Charging a towed vehicle's battery
I can not get my RVI battery charger to work towing my 2020 Chev Equinox. Is there another/better system out there for charging a towed vehicle behind an RV?

It is true that the MH will have an 'always hot' pin in the back, usually part of the 7 pin connector back there.
HOWEVER, as someone previously stated, do NOT assume that said pin is indeed hot. Check it with your voltmeter!
On Ford's F53 chassis, they do NOT wire that pin to 12V power from the factory. Neither do most RV manufacturers. We learned this with our Newmar we just bought a few months ago.
On ours, Newmar *did* run the wire from up under the dashboard, right out to the 7 pin connector at the back; They just didn't connect it at either end. I had to do that, before the charge wire would work.
Sooo, whether you use a simple charge wire or some kind of charger...Don't assume the wire thats supposed to be always hot, is. Check it with the voltmeter first.
