Also the 240 volt charging unit should have a fuse in it, you could try checking this.
My father had to change his, in his motor home about 2 years ago. He was told by the company that he bought it from, that it was fairly common for the cheaper units to fail due to power surges in caravan parks.
With the 12 volt side if your anderson plug on your vehicle is working, then it can only be a bad connection in the 12 volt wiring in the trailer or a blown fuse.
I would start by checking all fuses, I can see two inline fuse holder in your second photo and what looks like a 12 volt circuit breaker
Good luck with it.
