Need a Newer Toad - 7 passenger SUV - Commander orExplorer

Very happy with my 2015 Ford Explorer. Weighs in at 4700lb, tows beautifully, seats 7 comfortably, supper easy hookup. Put in Aux and go. I do have a trickle line in the umbilical, but is was available in the MH so I used it. I understand (perhaps incorrectly) that the 2016 model wants you to disconnect the battery. I have no idea what that would do to system memories, such as driver favorite seat position, radio, clock, etc.
