POSITION racks in top and bottom thirds of oven. Preheat to 325F. Line 2 large rimmed baking sheets with parchment.
COMBINE oats with nuts, coconut and pepitas in a very large bowl. Sprinkle with cinnamon and salt. Stir oil with maple syrup and vanilla in a small bowl, then stir into granola until well coated. Divide mixture between prepared sheets and spread out evenly.
BAKE in top and bottom thirds of oven, stirring every 12 min and switching sheets halfway through, until light brown and toasted, 30 to 35 min. Transfer to a rack and let stand until cool. Toss with dried fruit. Granola keeps well in an airtight container at room temperature for up to 2 weeks.
