Can anybody advise please ?

Under one bench seat behind the passenger seat is the usual fuse/relays that control the fridge and step, one is a 20amp fuse. This has blown but everything works, I have replaced it and it's just fine so question is what's it for ?

Fridge ?? Maybe you would not notice if setting to 12v and then driving...
Charger ?? If you been on hook up maybe not noticed alternator not charging the LB.

If you have two leisure batteries, then this 20amp fuse may between them, in which case everything would probably continue working but only off one battery. If this is the case you need to find why the fuse has blown.

Fair shout, I do have two but wrong side of the vehicle, both charge/discharge just fine.
It's an odd one for sure.

Leave it out - then wait until you find something that isn't working? Or replace the fuse with a 12v say 5 or 6 watt bulb. When / if the bulb glows something is trying to work via the fuse. Or replace the fuse with a meter set to 10A. When / if you get a reading something is trying to work via the fuse.

Thanks but as I said it was blown when I found it and everything works ! I have now replaced it with obviously no change.
