Welcome Riley! Just a note about your issue(s);

There are 2 sources of power in the RV, 12vdc and 120vac. They work independently of each other. Lights flickering would be 12vdc. If the outlets don't work that's 120vac - 2 different animals and you need to know which one is malfunctioning. I've had lights flicker, go off and just weird things in general when I had a battery that was dead cannibalizing the 2nd battery until everything was fritzy. Replaced both batteries. Your converter could be fried, if it was faulty it could have fried the batteries....??? Before just replacing the converter because someone who hasn't laid eyes on it said he thought it was bad I would suggest a little testing. I still don't know how you lost the receptacles due to anything from the converter.
