First build — what order should I do everything in?

I've just bought a 2016 Renault Master LWB and I'm planning my first ever conversion. I've watched loads of YouTube videos but I'm still confused about the order of operations. Should I do electrics before insulation? When do I fit windows? Should the floor go in first or last? I've got a rough plan but would love to hear from experienced builders about the ideal sequence to avoid having to redo things.

Here's the order I'd recommend from doing 3 builds:

1. Strip the van completely (remove panels, seats, bulkhead if needed)

2. Treat any rust spots

3. Run main electrical cables (before insulation covers them)

4. Insulate walls, ceiling, and floor

5. Fit windows (before cladding but after insulation)

6. Install subfloor and flooring

7. Fit roof vent/fan

8. Wall and ceiling cladding

9. Build furniture frames

10. Complete electrical (lights, sockets, consumer unit)

11. Plumbing (sink, water tank, pump)

12. Fit kitchen worktop and appliances

13. Bed frame and mattress

14. Heating installation

15. Final trim and finishing touches

The most important thing is to run your cables BEFORE insulating. Trust me, fishing cables through insulated walls is a nightmare!
