noise around fuse box area

I recently replaced my [email protected] battery.  The battery that came with the camper would last a month without being plugged into shore power.  After my new battery was charged it only lasted two days.  Also there is a noise coming from the fuse box area that sounds like a whirring airplane.  I am wondering if something is wrong to where the new battery is being drained.  Electrical problem?

    Sounds like the fan in the converter is cooling it and that would make a whirring sound. Normal. The battery not staying charged is not normal. Might be a parasitic electrical drain somewhere, something is on, or you got a bad battery. Enter “battery drain” in the search engine and you can see many posts relative to your issue. Some with solutions.
