I sure don't have an ounce of advice, Just wanted to give you my sympathies!!!
Since we only have the "icebox" or cooler in our camper- we think we just may get one of those coolers that plug into the car cigarette lighter spot for now. I noticed that car manufacturers obviously have thought of those sort of coolers- because I'll be darned if there isn't an "outlet" in the back of our new VUE!
If we like to use that sort of cooler- I just may turn the fridge spot in the camper to a storage spot.. we'll see.
BOY it's expensive to have appliances looked at, isn't it?? How OLD is that fridge? That may help you to decide.
