How can I tell on my 1990 Jayco deluxe series 1006 pup. I don't know the old manual doesn't say much about it. I don't know if its been removed. I would just like to pump water to wash hands and face. I'm going to look through that manual again. How can I tell if my heater work not by propane but by electricity once I plug it in. I know I'm just pitiful. I brought this camper in December of 2018 and haven't plug it up yet and still fixing it up. I brought new tires, new roof vent, and new jack and spare tire holder. Wash cushions, re done some fabric and brought new tile for floor. Slowly but surely I'm getting there please be patient with me camping friends.
