Note that not all RV systems work this way.
So, what I was pointing out (a bit tongue-in- cheek,) was that the whole entertainment system might be powered off of that mystery 15
amp DC circuit. Assuming, of course, that ST stands for stereo and not something else. (Frankly, it would have made more sense to label the fuse ENT if that were the case.)
BTW I do believe that the fuses are on the converter and, thus, those circuits are all 12 volt. General
rule of thumb for an RV: Breakers are used for 120 volts AC, fuses for 12 volt DC. Moral - keep a supply of fuses in the RV.
