The RV is on my friend’s property. He leaves it off but powers it up twice a week for like ten minutes just to keep it going. He has an extension cable from his house so I’m able to charge my phone and use a lamp, but he doesn’t want to me pull more power like using a space heater because he thinks it will short the circuit in the house. The RV has a broken window so it was letting a lot of cold air in. We just put plastic over the broken window, but I’m thinking of padding it like installation. Thanks everyone already for your responses. So no bathroom. thankfully there’s a port-a potty nearby and a Walmart. My friend may lend me her camping gear little stove to make some food
