After having back surgery, I can no longer carry the 6-gallon water jug I previously used to add water to our RV’s freshwater tank when dry camping at national parks. Now I use a couple of 1-gallon milk jugs to add water to the tank. Since it’s difficult to pour the gallon jugs directly into the water fill, I discovered that a 16-ounce plastic soda bottle fits perfectly into the neck of the water fill. I cut a rectangular hole in the side of a soda bottle to make a no-cost right-angle funnel, which makes it much easier to pour water from the jugs into the freshwater fill. It also works well for adding bleach to the tank for springtime water-system sanitizing.
