Question:

I have a 2024 Equinox and Chevy has a bulletin that the negative of the battery has to be disconnected while towing. I want to get a braking system but how is that going to work when the negative of the towed vehicle is disconnected? I was looking at the Duo but want to make sure you say it will work this way. Thanks

Expert Reply:

The Stay-N-Play Duo # SM99251 you're looking at will get power from a charge line kit # RM-156-25 which goes from the motorhome to the vehicle battery and will send power while the battery is disconnected using # RM-766.

To finish your flat towing setup, you're also going to need a base plate kit # DM9519332, a wiring harness # RO94FR, and a tow bar # RM-676.
