Where we usually go is only about three hours away from home. We have a pad beside the house with a 30 amp outlet so we just tow home, take the trailer and dump after we drop our boat off at the house and then park the FW and clean it out. Since this week was probably out last trip for a while, we emptied the fresh water and hot water tanks, took all the food out, washed the sheets, blankets and comforter. We will then clean the outside and inside, when the weather gets a bit better. Right now, it's totally overcast with temp around 54 degrees so not a lot of outside stuff right now. Back to the original question, we usually wait until we get home to clean anything up as we have room at the house to do so at our leisure.
