2014EL w/5.4. Got home from 3600 mile East Coast round trip. Florida was great ... 90's & sunny. Pool action was legendary! Experimented with 2H vs 4A gas mileage. Seems like 2H gives me 17.1 vs 4A 16.9. Very unscientific test. The Expy with 110K drives like its brandy new and it is a great cruising vehicle. Did not lose any oil and its just starting to take on a slight amber color after 4K miles. The cooled seats are great for Swamp Ass. Sirius rocks. One time interstate stopped traffic in SC, but I thoroughly enjoyed it.
