I have a 2020 FWD that I flat tow behind our motorhome. The owners manual says it should be towed with the transmission in neutral and the switch in the "ACC" position. I do that however I have intermittent connection issues with the charge wire running from my motorhome and never know when I will have a dead battery when I get to my destination. Other than the computer and clock resetting is there any reason why I couldn't install and switch a battery disconnect once I shirt it into neutral. It's been dead several times due to not charging and it always seems to be OK afterwards. It's a real P.I.T.A.
