Towing a 2011 Equinox

I have also put in a relay that connects my RV and toad only when the coach is running so I can keep the two attached without any battery issues.

The rear 12V power is hot with fuse pulled.

Ava,

I already have the RV-to-Towed set up configured so that a relay automatically opens the fuse path when the lighting umbilical is plugged in.

With the Equinox, no matter the key position, the lighter/power port is DISABLED when the fuse 32 circuit is opened or the fuse pulled. I NEED the power port to be operational to power the Brake System.

I was planning to attach the charge line to the HOUSE battery with a power relay between the RV and Equinox batteries.

The power relay would be pulled in by the alternator output. That way the alternator would charge both/batteries only when the engine is running and the Equinox would NOT draw from the house battery when the engine is NOT running.

For example, if we stop for the night and do not unhook the Equinox, the batteries will be separated and a load on either end would not draw down both batteries.

Should be fine if you are charging it from the RV. You might have to tow it for a few hours then try it to be sure. They also make an easy fuse disconnect switch if needed.
