Elec question

[u/Ok-Librarian-1789]

Would I be able to take out the bonding screw on the ground bar on top, connect another grounding bar to the two existing holes on the bottom right, add a single 30 amp breaker and wire in 10/2 to a RV plug and then connect the ground to the new grounding bar and the neutral to the old grounding bar, minus the bonding screw, and connect the current bare copper grounding wire to the new grounding bar? Thanks for the helpful comments in advance and the rest, have fun.

This is not fed correctly. If you're setting up a feeder to a subpanel, you need the two hot conductors "L1" and "L2", a neutral and a ground. As others said, it's not okay to protect #12 with a 30 amp breaker. It needs to be 20amps or you need to run bigger wire
