If you are at a camp ground you might get some good help from another camper there with a fifth wheel.
It sure sounds like a 12VDC problem...
All of those things get powered by the converter/charger unit when plugged into shore power and the battery. Need to look for some blown fuses...
If the battery is run down you can always nose the truck up to it and use jumper cables - be sure to connect the cables correctly to the battery terminals or you will have more blown fuses to find.
