Battery disconnect switch is on. I never use it, but did check it just in case. When you say large 40 amp fuses, do you mean typical automobile type fuses? Because i checked and replaced all of them. If memory serves me correct (Im at work right now and cant look at the RV) there are a handful of 15 amp fuses, one 20 amp and two 40 amp.
Also some trailers have a breaker on the trailer tongue near the battery. It might have a rubberized cover covering it. It’s a physical push to reset type affair. At least on the ones I have seen.
