All of the items you have listed as working are 120 volt AC devices. They only work if you are on shore power or generator power.
The items that are not working are
12 volt DC powered. Which means they are powered by the battery or the converter.
Since it appears that none of the
12 volt equipment is working. You are obviously not getting battery or converter power.
Have you checked for voltage at the
12 volt fuse panel?
Have you tried a battery charger?
How did you check the fuses?
Are the larger fuses tight in the holders?
Have you tried replacing the larger fuses with new fuses? Making sure they make good contact in the holders.
Can you post pics of the fuse panel? We could tell you where to place the meter leads to check for voltage.
