Your converter is doing as it name says, and "converting" AC voltage into DC voltage......in able to provide power to the things in your trailer that run off of DC power. Your trailer has a 30 amp 120 Volt AC cable. Your converter is capable of outputting 55 amps of 12 volt DC power.
120 volt AC is not the same as 12 volt DC.
For example (and this is just a guess), your converter might use 8 amps of AC power to output 55 amps of 12 volt DC power.
The basic function of a converter, as the name suggests, is to convert 120 volts AC electricity into 12 volts DC power.
