I can imagine you're pretty cheesed off PKSES but welcome to the forum anyway.
If you give more detail re the MH we might be able to help - model, year ?
It's odd that one leisure battery is gone while the other hasn't as they're usually wired so that they work as a single.
The fact your fridge isn't working is probably due to needing 12v in its functioning.
Hope someone will be along soon with better info about the 12v.
