Battery losing charge

Just bought an 04' Fleetwood Prowler & after a few days replaced the battery since it appeared not to take a charge. (drove 4 hrs before trying to open slide out) Installed a fresh battery the next day & it also drained after very little usage all the while plugged into a 110v outlet. The trailer plug to the truck had some fraying but I taped it. Is this likely a converter problem? If so what should I replace it with or should I start with the trailer plug? or is there some troubleshooting I can start with to diagnose?

    When driving, the converter is not a part of the charging circuit so the converter is not responsible for not charging the battery.

    Have you checked the battery disconnect switch? If you have a voltmeter check the battery voltage when the RV is not plugged in and again when it is. The voltage should be higher when it is plugged in. Check the battery wires for loose or corroded connections and for blown fuses.

    I would check the converters output but after driving 4 hours the truck should have charged it enough to get the slides out.
    You may just have a fried converter discharging the battery but you need to make sure the truck is charging too.
