I shared your concern, based on those same threads, until I took delivery of our 2022 Elite II, Hull #1291, last November. My inspection of the factory wiring, bus bars and other electrical components visible through the access ports and hatches in our trailer appears to me to be done with greater care, and often with higher quality components, than are shown in John Davies' photos from his 2017 Elite II. This suggests to me that Oliver has raised the production quality of the electrical installations in the interim. It made my feel a bit better about paying so much more in 2022 that Oliver was charging back in 2017!
In fact, my impression upon inspection was that the electrical issues noted in John Davies' many posts appear to have been passed on to the "right" people at Oliver, and that they have since implemented needed improvements in component and production quality. Time will tell if our 2022 electrical system is less trouble prone than earlier models.
Ollie-Haus, I hope you are pleasantly surprised by the quality of the electrical components and work in your 2023. As you are obviously more knowledgeable about such things than I am, I look forward to reading your observations following delivery!
