As an experiment prior to going to fulltime RVing, our family went to Thousand Trails Orlando RV for a couple of weeks. The things we learned were fascinating!
First, I learned that if I don’t turn the park/city water on, the water pump needs to be on, and will pull water out of our main water tank. Our main water tank is 100 gallons, and we, as a family, burned through 100 gallons of fresh water in just over 32 hours! My hopes for boondocking out west dropped into the tanks along with the fresh water.
