Wiring Help please

[Nickcatt]

I am in the process of wiring a "flexi day van camper" I am having a split charger fitted, but was wondering if all of my outlets/lights need to have the negative taken back to the split charger earth or can I use the the welded stud vehicle earth points located in the rear of the van

Keep the earth wire runs as short as possible. Use the nearest vehicle earth point, which may be your split charger earth point.

Yes.
