Instead of using a water hose just fill your water tank and use it. When you are gone I would be more concerned about the water lines than the tank. Pump some antifreeze in the lines if you think it will stay freezing for a few days or more.
This. And if it's cold while you are there, just fill the tank and use from it.
If you have electric (and that is what most people mean by "full hookups") you could leave a small electric space heater turned on, to keep the inside temp up above freezing. It won't take much.
You should have a bypass on the water pump that will let you suck antifreeze up with it. You should also have a water heater bypass so it doesnt get antifreeze in it. Just drain the water heater, and run some antifreeze through all the lines until you see pink coming out. Be sure to get RV antifreeze (nontoxic) pink stuff, instead of automotive antifreeze.
To be on the safe side, you could drain the freshwater tank.
This won't take but a few minutes, and a few minutes to fill the tank and flush out the lines when you get back. The antifreeze may leave a slight taste in the water lines after its flushed, but you could take some drinking water.
