Between 2006 and 2013, Klepper assisted his friend Rodrigo Trevizo, park ranger and caretaker for the property, with the various chores required to keep the ranch in operating condition. The two excavated and repaired the primary water network, cared for the livestock, cleared brush, and maintained a small, solar-powered electrical system.
