You should always travel with full water and a roll of duct tape.
Why full water?
1. It lowers the center of gravity of the trailer which helps the trailer to track better and to be more stable around curves.
2. You, or a passenger might have to use the "john". Yes, then the toilet can be flushed. You know what happens when mother nature calls.
3. If you blow a radiator or heater hose, no problem. Wrap the split hose with duct tape, fill the radiator with water (that your going to get from where?) put the radiator cap back on, but loosely, so that pressure cannot build up.
That may only get you another 10 to 20 miles.
But, you can stop, and repeat the process, and get the water, from, now you know where.
Traveling with a full tank of water across the USA, would cost you about another 1/2 gallon of fuel, or less. Traveling with an empty water tank, is false economy.
Lastly, Brian, you won't have any more air in the water lines to worry about.
