Well here is the update. The heater shorted out causing the 5amp use to pop. The heater shorted because I have electrical problem with my converter. (I brought out a mobile RV guy after I popped the second 5amp fuse.) The refrigerator is as vintage as my RV and I knew it was going to need replacing or some serious maintenance. I am now thinking about just yanking it out and replacing it with a residential fridge. I will do very little if any boonedocking so running on batteries is not a concern of mine. Looking for opinions on this subject and any red flags that I need to be aware of. I know about the size limitations as far as getting it inside. Has anyone done this and if so do you like it?
