Well thanks for the response. I cant find the Converter, I looked under the only vented space inside the Motor Home, under the refrigerator and I cant see it it anywhere and if it is I don't see how anyone could get to it to check for a blown fuse to it must be somewhere else.
Looks like another night of getting up every few hours to start the engine to recharge the house batteries which does not take long at all and then I have another couple hours B4 I need to do it again to keep the heat up and the underbelly heated compartments warm so we don't end up with any freezing problems there.
Tomorrow Thor will be open again and I will call them to find out where they put the Converter
