I have a 2014 Fleetwood Storm Class A all batteries are discharging within 4 to 5 days even with everything off. I have no idea what is causing the discharge. Anybody have an idea? DB
TV boost for the antenna. Very easy for it to be on and for you to forget about it. Also, lights in bays - during the day you may not realize they are on. Parastic loads - not much you can do about them. I would assume you have a battery disconnect switch in your rig.
