I never use the sunroof, and it is a potential source of leaks. I suggest an option to substitute a solar panel for the sunroof. Maybe it would keep the Low Voltage battery charged. A solar panel bed cover would also be nice.I wrote to Ford and suggested a Solar outlet integrated within the tailgate's array of outlets. If you wanted to carry an industrial home size solar panel or any solar panel in the truck bed the purpose would be to use the trickle charge to help maintain battery temp vs using the main battery. Any surplus would then go to the main battery. Very help suggestion say in cold climates where Lightning owners are already parking their trucks outside. Why not use some of that sun to generate a bit of heat?
