We are set up to tow behind our coach using the M&G braking system. Having difficulty finding in the owners Manuel the exact sequence to shift the transfer case for towing. Would appreciate anyone’s step by step instructions.

I'm not smart enough to attach a file. Send me a PM and I'll send you what I made up for our 24' Tahoe. Did you install a Battery disconnect?

Here are my steps from memory.

Engine Running
Shift transmission to Neutral
Push the 2WD button 5 times
Watch the dashboard for the indicator to show your transfer case is in Neutral.
Shift transmission to Drive to make sure there is no movement.
Shift transmission to Park
Make sure Parking Brake is not set
Turn off engine
Put ignition in ACC mode (foot off brake, push start button)
Turn steering wheel to make sure it will not lock
Disconnect battery

To put it back in 2WD:
Reconnect battery
Turn on engine
Shift transmission to Neutral
Push 2WD button one time
I've found that after a long tow, sometimes, it will not shift into 2WD and times out. Shift to 4WD if it fails. Then shift back to 2WD. That's worked for me.
