We purchased a new 2015 F-150 4x4 because they are towable four down by electronically shifting the transfercase into neutral. It also adds the ability to haul our motorcycle when towing.
One thing not in our Ford manual was the need to set the antitheft sensors to "peripheral only". We didn't and we couldn't figure out how to turn the alarm off. Had to wait and call Ford in the morning. They insisted it was in the manual, so we asked what page? It wasn't where they said. My DW made up a nifty checklist to go through when enabling neutral tow.
