I found the definitive word from Honda in their 2019 6 speed Jan 2019 Owners Manual:
....and it wasn't easy ! .....
HondaTowing Behind A Motorhome
Models with continuously variable transmission
Your vehicle is not designed to be towed behind a motorhome. If your vehicle needs to be towed in an emergency, refer to Emergency Towing.
Improper towing such as towing behind a motorhome or other motor vehicle can damage the transmission.
Models with manual transmission
Your vehicle can be towed behind a motorhome. Perform the following procedure before towing your vehicle:
Shift to Neutral.
Release the parking brake.
Turn the ignition switch (or power mode) to ACCESSORY. Make sure the steering wheel does not lock.
Turn off all electrical devices. Do not use any accessory power sockets. This can prevent the battery from running down.
