where 2 get water for RV before you reach your destination?

There afraid the water tank will drop out of the camper.

30 minutes is a long time filling up!

Others may not want to travel with water depending on what they travel with. When i had the pop up the extra weight and where it was located added to sway. Not all campers are the same. I have never had trouble with campground water being undrinkable or bad. Use a filter and sanitize your tank and lines.
