Seeking wiring diagram 2021 Coachman Leprechaun 300BH

My class C RV has a television cable issue and it is likely at the splitter since tv hookups exist on both port and starboard interior and exterior.  Port side is input entering near the water connections and under bedroom nightstand.  I’ve tried tracing the lines but a bit tight for me to reach everywhere.  Any tips or links would be appreciated.
