Wiring Clean Up Suggestions

Everything is soldered well and protected with heat shrink and have the appropriately sized fuses. I know the wiring itself is good. My only regret is using 14 gauge on the bed outlet. I'm within spec by using 14 gauge on a 15 amp circuit, but I wish I had oversized it to 12 gauge. My fridge has a max amp draw of 8.4 when the compressor kicks on and is the only thing that I use the bed outlet for.

Open to suggestions to the best way to make the wiring look better.

Unless I'm missing something, I think my best option to clean everything up is to drop the 8 accessory wires (4 pos/4 neg) to bus bars and run cabling oversized back to the battery like 0 AWG?

Would love some of your thoughts.
