Help 2018 Equinox

Question

I have a 2018 Chev. Equinox premier every time when I tow 4 wheels down the battery goes dead. What am I doing wrong? No braking system attached,and a hot wire going from the coach to the battery with the center pin on the auto reading 12 volts to ground. Here is my procedure:
1 Engine on shift to N
2 Push switch (no foot on brake) now in ACC
3 Auto lights to off
4 Radio off,button held down
5 Heat off and AC off
6 Turn settings on
7 Turn display off
What am I missing or what am I doing wrong? I will thank everyone ahead of time, Ole B needs help

Does the owners manual require you to leave it in the ACC Position?  That will kill the battery in a heart beat.  Do you have 13+ volts on the Equinox Battery when hooked up to the coach?  If the charging line is hooked up properly and powered, you should have 13+ volts on the battery with the coach engine running.

ACC must be on when in "N".  Over 13 volts when coach running.

Does the owner's manual require that a fuse be pulled?  On my Traverse, a fuse must be pulled prior to towing.

Are you hooking up a ground wire to the coach?

Seems GM keeps fiddling with things. I received an email from them indicating I needed a battery tender installed on mine. I went with an RVI unit and my issue went away. May look into it.......Dennis
