@kyunam The drive up Santiago is easy. Nothing technical except watching out for the off-roading trucks that go flying up the mountain around the blind turns and you come face to face unexpectedly. Go! It's great fun. And there's an off-roading "park" at Wildomar that has lots of trails to go on.
Santiago Peak lookout. First drive up the mountain in the R1T back in Dec. 2021. Mine is the white one. Cooper is my Lab who loves exploring as much as I do!
