2010 Rockwood 1920 BH - Electrical issue

I have a 2010 rockwood pop up camper. I am plugging into my house (110) through my garage, using a dog bone adapter to plug into my camper. For some reason I can not get the fridge or the over head interior lights to come on. There is an electrical plug inside the camper that I have plugged into with a light and it turns on. I have tried switching the breakers on and off with no fix. Any ideas?
