Hi to you. Congratulations on the new JayFlight and welcome to the forum.
RV electrical codes and practices are very different from homes etc. I'm not sure what others will say, but IMO neither Jayco nor the dealer are likely to change it as a warranty issue. Your dealer might change it if you ask or you might need to change it on your own.
