I don't quite understand this.
There is usually a charge line on a TT, or 5th wheeler. Even a camper may have a charge line.
As for the toad charge line it helps keep the vehicle battery up since power to any braking systems is being supplied by the toad battery. Often the ignition must be in an accessory position which will discharge the battery as well.
Some towing vehicles need to have a fuse and relay installed to activate the toad charge.
