Get some portable battery or solar lamps/lanterns to use inside at night as needed. Keep hot water and water pump off until needed. If you keep the hot water heater on, it will use electricity to spark the ignitor to try and keep hot water. How water will remain in your HW tank for hours when you turn it off. Just turn the the HW tank and pump on when you need to. You can avoid the fridge issue also if you just take a cooler. Matter of fact, hit your battery disconnect when not using anything in the trailer. It will turn off your detectors as well. But you won't need them if you don't have the propane running or using electricity. More or less, you will just be in the trailer like it's in storage. I would definitely add a second battery, it will extend your time. But if you can limit yourself to camp down to more barebones and turn things off when not needed, then it will help.
Otherwise, carry a generator or get at least 100watts of solar. 40 watts, might top off your battery in a day if you don't have anything pullign power while you are doing it, but you would probably need to not less than at 70-80%. A generator can have them charged back up full in an hour or so, depending on how low you drain them.
We are rather new to the dry camping thing and have been reluctant at doing it, but we are doing it more and more and realizing what it takes and what we can do to make it better.
