Though I travel a lot, just crested 2 Million miles with Delta Airlines, I have driven long distances this past year. Atlanta to RI and back. And I put 12K miles/year on a 2003 F150 I've owned since mile 3. I own a Passport 9500ix, circa 2011. Not sure I get all the acronyms: LEO must be Law Enforcement Officer, yet I'm a quick study.
