God might have a set of drawings. Other than it all depends on what wire is available and which tech is working that day. It varies from RV to RV. There could be 2 RVs being built side by side and each one will have different wiring and plumbing. Good luck!!!
How or where can I get electrical drawings for my 2021 GS Vista 19CSK
I think Gingersdad about nailed it. I have a 23RSS and have spent more than enough time scratching my head figuring things out. Any particular circuit you are interested in?
