Hello Samschoy
Welcome to the forum.
I hope we can help but there are a few things that we need to establish first of all. It can be very difficult to diagnose a problem like this over a forum, often parts of the system needs to be checked in particular ways which obviously we cant do remotely.
I see you have an Avondale Rialto from 2002. My guess is you will have a Truma water heater, but please confirm the make and model.
You tell us the electric is "tripping" but exactly what is tripping, is the mains RCD or one of the MCB's, or is it something else?
One of the more frequent problems we do see with water heaters is a failure of the mains heating element. This will usually cause the mains RCD to trip, This element has nothing to do with the 12V system so changing the battery will not change the the symptoms. If the Mains RCD trip operates this will prevent the 12V charger from working.
Its very unlikely anything would flatten a 110AH battery over night, unless someone has tampered with the wiring,
I feel you might be best getting a mobile caravan engineer to check your systems to find what's draining your battery and and if necessary change the element on your water heater.
