Hi! me and my partner are planning our electrical system in our campervan. Does this look okay? Does anyone know what diameter of cables are needed? We are both newbies at this :P !

Rate my campervan schematic, does this look okay?
You need to compute your loads in amps.
Your loads, in amps, will help you decide your fuse sizes.
Your fuse size, determines your minimum wire size.
The wire length ( voltage drop ) may require even larger diameter wire.
Are you going to have a communications wire and/or a control panel?
The schematic looks OK.
I don't see a BMS, so best add it if the batteries don't have them built in.
I assume you have a proper RCD between AC in and the multiplus.
The AC in earth must go to the vehicle body, not shown.
AC to consumers must go through a consumer unit with suitable breakers, tcd/master switch
I assume there's a fused distribution system for DC loads.
I suggest adding a GX device, such as a Cerbo to control and monitor the system.
Not sure where you'll be going, but some European AC supplies have Neutral and Line reversed. Make sure you have a way to check and a reversing connection if appropriate.
For current/ cable sizes, treat every run independently using one of the online calculators.
