Tom
There is fresh water and a dump less than a mile away if needed. For some boondocking becomes a challenge to last the week while others just plan on making the trip to the dump station mid-week, your (or Theresa's) choice. As is mentioned in the info on QZ arrive with full water, fuel, and propane and empty holding tanks.
We lived in Sterling for several years, are you close?
We all look forward to meeting you both!
