2018 Chevrolet Equinox battery dyeing

Ok bought this new. installed a Toad Charge. First time out after 6 hrs the battery was dead.
This year stopped at every rest stop and ran the engine for about 20 min ea time. Coming back fro San Antonio Had a dead battery 30 min out and jumped it ran it for 20 min and left for the next rest stop. Dead battery. Had to have wife drive it back to Mesa, az.
Followed Chevy's instructions on how to tow it. Accy mode, Trans in neutral, parking brake off.
What am I doing wrong? Am I the only one having this problem? Is there some fuse to pull?
Am thing of getting a dolly. Don't want to do that but can't change cars.
Help plz

    The 2018 and newer Equinox and Terrains pull a lot of power in Accy/tow mode. Your charge line might be too small. 12 gauge wire is needed. I've been fine at 5 hours tow time but had a dead battery after 8 hours. I'll always start and run my Nox at 4 hours max unless I'm nearly there.

    I had a Buick that drained the battery overnight. Testing showed no power drain on the battery. It turned out to be bad voltage regulators. After changing the alternator three times, it still did the same thing. It turned out the "new" regulators in the alternator were bad. It took over a year to solve the problem.

    dave have you tested the 7-pin connector on the back of the coach to make sure there is power there? I am assuming you have a 7-pin connector, either way etrailer has some good info on the wiring setup, Trailer Wiring Diagrams scroll down for the Vehicle Side 7-Way
