Here is the deal. "I have an electrical problem" is not a good way to get help. We don't have a clue what kind of camper you have let alone what your issue might be. Detailed troubleshooting requires detailed information on the problem. Sometimes photos help.
I doubt someone is going to jump right in with "the solution" with so little to work with.
And yes, you should be concerned about blown fuses and arcing in the panel.
