Question:

Would the Tekonsha 2024-07 12v battery charger be a good choice to install on my toad? I just dont want a dead battery at the end of a long day. Thanks

I do have a better option for you but the Tekonsha Two Stage 12 V DC Battery Charger part # 2024-07 is mainly used to charge a breakaway systems battery which is much smaller than the 12 volt battery you have on your toad. A better option for you would be to run a charge line kit like part # RM-156-25 from the tow vehicle to the toad. If you are towing the vehicle behind an RV than you would also most likely need a charge line kit for the RV like part # RM-156-75.

I have attached an installation video of both charge line kits to give you a better idea of what it takes to install them.
