lost on why it's blowing fuses.

Sounds like a short to ground, on the positive wire between battery and converter.

Disconnect battery and shorepower, and follow that positive wire to the converter. It may go through a junction box under the trailer. Check for pinching, chafing, signs of sparks, etc. Inside the junction box (if there is one) look for loose connections, signs of sparks, corrosion.

Put the fuses back into the fuse panel, connect shorepower (not the battery), if 12 volt systems work, that eliminates coverter as the problem.
