Anyone towing 4WD Suburban or Tahoe (2015 model)?

We currently tow a 2004 4WD Avalanche and it is a piece of cake. We just hook it up, put transfer case in neutral and are ready to roll. Nothing else must be done; key can be removed and vehicle locked.

I read somewhere that one or two fuses might have to be removed in order to tow the new Suburban or Tahoe and maybe leave the key in the ignition. I would prefer not having to do this. Does anyone have first-hand experience?

Thanks.
