I think you need to clarify...
Is it hot when ...
driving.
parked with fridge etc on
with or without mains hook up
Does the battery charge and hold it’s charge ok

A battery should normally not get really hot. If so, it might be at the point of boiling due to internal short circuit?

And this one:

Does the battery charge and hold it’s charge ok

Hi thanks for getting back to me
I noticed the battery was very hot after a day on hook up
So I unplugged immediately
It was cool in the morning I had the fridge on all night that was ok and battery still had plenty of charge in it
Didn’t go far today just about an hours drive and it wasn’t warm
Not plugging in the hook up unless I need it thought I could get through the holiday that way
Hope that all makes sense what do you think?
Cheers Neil

I haven't touched my batteries while on hookup, so I can't really tell if this is normal or not?

Next time you Plug into the mains, if the Front battery gets hot, check the rear one in the base of the rear Wardrobe. How old are the batteries?

I haven't touched my batteries ever.

My first thoughts would be that the battery has had it. Worth comparing the two batteries as suggested by @WelshGas as a starting point.
