We’re going on our first longish dry camp. 4 days/3 nights We are planning to fill our fresh water off city water before going.I have a fresh water pressure regulator, and an inlet hose.Tell me what to do so I don’t overfill or cause some problem.

No biggie if you fill it right to the top.It will run out via the overflow if you go around a corner and the water sloshes over.

Fill it slow and easy though. The air must escape out the overflow tube which is a smaller diameter than the water inlet. Fill it too fast and the air will burp out the inlet and get you wet.

Do you KNOW that you fill the tank via the "city water" connection or are you assuming that ? Many have a separate "port" for filling the tank directly from a hose.As has been said, overfilling should not be a real problem but some might slosh out the overflow the first few miles.If you can SEE the actual tank, you might be able to see the water level in it too.
