Can any electrical gurus please check my plan so far? So i have decided to do the first fix of the electrics today. My plan is to have a 12V Fusebox behind the furniture, so i have run a 16mm2 flex cable from my busbar to the rear of the van, via the B Pillar and under the window:

The negative runs to the earth point on the back quarter:

Both cables are protected with split plastic piping, and cable tied down, but i just wanted to check with others that it will be ok to run it through this insulation. I don't see it why it would be an issue, i just wanted to double check. The cable will be fused by a MIDI at 30A, to run: Fridge, Lights, USBs, Hob Ignition, Water Pump.
Additionally, my current plan is to have the cables come out of rubber grommits on the little panel on the C Pillar, and then up to the back of the cupboard for the fusebox below. But is this the best idea in terms of location for the fusebox?
