Hey guys,
Sorry for never getting back to update everyone.
I had a technician come out and I was right. I think it was the reigniter in the refrigerator that was bad (leaking propane)? He replaced that and fixed the electrical so the outlets inside worked. A couple of days later the whole camper lost power and I had to replace the converter. Also added a battery, which I had never had before. So now, the refrigerator is running on electric, the way it should have been all along. I obviously had no idea that's how it should be done because I'm totally new to this and learning as I go.
But since the technician came out (he was super nice and gave me a great price) everything has been great. Two tanks of propane are lasting forever, and it's great to be able to use the outlets in my bedroom. Only thing left to do is get a propane detector, because mine definitely did not come with one.
Thanks so much again to everyone that helped try to figure out the problem. I'm very happy that my suspicions were confirmed, because it shows I'm learning. But I will remember everything everyone suggested in the future should more problems arise.
Have a great evening everyone :)
