I have a 2020 Equinox that I flat tow 4 wheels down behind my motorhome. The battery discharges after about 3 hours of towing. Do you know of any reason I could not disconnect the battery when towing? Would it hurt anything? This is how I towed my Ford Focus prior to getting the Equinox. I called GM tech support and they said I shouldn't because I would have to "reset everything"?? I called the dealer and they said it would not damage anything. Would like to know if anybody of this forum flat tows with battery disconnected.
