Autocruise stardream Where is the RCD

Tilts96

i have an autocruise stardream 2008. 

The electrics have just gone down on site. I have checked the cable and the site post etc so all that is fine. I have had the seats completely out and all the cupboards and cannot find a mains unit with tripswitches
anywhere in the motorhome  - there is a distribution unit behind the driver seat only And A control panel by the door 

Does anybody know where it might be? - it must have one  - right?
