Recommended Charge Line for Toad Behind Motorhome


Can you just run a charge wire from the motor home or is there some other reason the ground has to be disconnected when towing a 2015 Yukon Denali


Expert Reply:

The battery of your 2015 GMC Yukon must be disconnected to protect your electronics when towing. If your supplemental braking system uses power, then I recommend the Roadmaster Battery Charge Line Kit for Towed Vehicles # RM-156-25 on your vehicle. If you don't have the charge line on your 7-way or 6-way of your motorhome, then I recommend # RM-156-75 for that charge line kit.

To make disconnecting and reconnecting your Yukon battery easy, I recommend the Roadmaster Automatic Battery Disconnect with Switch for Towed Vehicle w/ Supplemental Braking System # RM-766. This allows a simple switch to disconnect and reconnect your battery for towing or driving.
