Camper Van Electrical System – Looking for a Review Before Final Installation

Hello everyone,
I am currently finishing the design of the electrical system for my camper van and would like to get some feedback before starting the final installation.
I have prepared a complete wiring diagram in PDF format and would appreciate it if experienced members could review it and point out any mistakes, improvements, or recommendations.
My main concern is making sure the system is designed correctly and safely, especially regarding grounding/earthing.
Thank you in advance for your time and help. If anyone is willing to take a look, I can share the PDF diagram. :blush:
