Question about freshwater tank use

All of the reasons above, plus if we need to use the “rest” room and there are no facilities we can use our own. I don’t like to fill it before leaving since 40 gallons of fresh water weighs almost 300 lbs. Most campgrounds without water have a fresh water fill station unless they have been shut down for winter.

I also try to find out in advance if the campsite includes water hookup.
