towing chevy traverse 2014

Hi wondering if anybody is towing a 2014 chevy traverse.

I have my ready to tow with a switch on the Batt 1 Fuse.
Is anyone else also pulling the onstar fuse and the ecm fuse in the battery compartment ??
I dont pull the above 2 fuses because i have a charging line setup to make up for any draw on the battery

Thanks

Ted
