Then you shouldn't have any problems.
I've only pulled my trailer full of water on a few occasions when I knew we were going to a state park and I trusted our home water more than theirs. I've also pulled into parks and had to fill the tank at a community hydrant. In most cases I travel with 1/3 tank of fresh water so if we get into a jamb, we can survive easily for the day without having to worry about water.
On one trip to AZ, this came in handy because we stopped at a place in NM and their water was expectantly not working. Sometimes on long stretches of a trip (700-800 mile days), I'll pull into a rest are and take a shower to refresh myself and then motor on.
