When I had a gas rig, I towed a Forester, w/ a Roadmaster Evenbrake System. At the end of everyday of towing the Forester battery was dead. Had to jump the car, then run car engine to recharge. I really got tired of the Roadmaster Evenbrake System. The last time I used the Roadmaster Evenbrake System it set the brake and did not release, while being toad with my currrent 400Hp diesel. This burnt up the brakes causing $1300.00 in damages. I trashed the Roadmaster Evenbrake System and had a SMI Airforce One installed. This system works well and has never left me with a dead battery.

I tow a '16 Impreza and have not had the issue. However I have a charge line from the motorhome that keeps the battery charged. I have 2 friends with '15 Outbacks that have experienced battery issues when their cars were new and they do not tow their vehicles. Subaru replaced their batteries under warranty and admit that the factory batteries are under rated for the electrical load. They were replaced with batteries of larger capacity.

You always have the option to run a charge line from the MH to toad. Multiple ways to do it from homemade to commercial units and the net result is the same - no dead batteries.

Tow a 2013 Subi XV, usng an RVI2 brake setup. Also use their 12 volt battery charger.
What is happening is that your Subi's electric system may be off, but your brake system is 12 volt, and hooked up however you did it to 12 volt outlet. Everytime you hit the brake on your rig, it causes the brake unit in the Subi to operate, thus drawing power from the battery. A long day of driving will drain it.
You need to run a charge line from your rig to the Subi, but I would recommend using some type of charger like the one I mentioned. It has a chip and when battery is charged, just maintains a float charge. Running a srtight line from your rig may overcharge the Subi's battery.

To resurrect a somewhat old thread:

I spent most of this week preparing a 2013 Subaru Outback, 6 speed manual as our new TOAD. Previously, we towed a Honda Odyssey and always had dead battery issues. Assumed the battery drain came from the Brake Buddy system.

As the Honda used a Blue OX tow system, that is the baseplate I installed on the Outback. While I considered running a charge line to the Outback battery, I deciced to add a 12 volt cigarette lighter power outlet that is only active when connected to the running coach. The outlet lives is the Outback glove box for the moment. I will use this outlet to power the Brake Buddy. First test drive today seems like all is well.

The only downside I can see is, IF, the TOAD got away from the coach and the break-away switch activated the brakes on the runaway TOAD, the air pressure would not be regenerated after the original activation of the Brake Buddy. Comments please. Is this a bad idea?

Next question: I used the four diode Roadmaster kit 154 to wire the lights on the Outback. The Outback has amber turn signals and seperate brake lights - which still work during non-TOAD use. Thank God. When connected to the coach, the turn signals and brakes share a bulb and the amber lights are not used, nor is the center brake light. Typical I guess. I would like to wire the Outback to use all the original lighting when connected to the coach. Has anyone done this successfully on the Outback? Is it really overkill? We plan to keep this TOAD for several years, so it would get much use. The coach has combined brake and tail lights.

Finally, I installed the Roadmaster Brake-lite Relay and it appears to do what it is meant to do. However, I would gladly pay someone to do that install if I had to do it over again. Hard work as you get older and your eyes just don't focus like they used to while you're laying on your back in the floorboard.

Good day to all and hope you'll share your wisdom.
