I am a window cleaner
rear doors or side doors once left open, the rear and front headlights stay on for quite a while,
as my work is stop and start, i.e. Within sometimes 50 metres, I have after moving van 5/6 times had the battery die.
waiting for fords on this one....but why can't you change settings for the rear lights delay?
not worried about the LED in back of van, it's the rear tail and headlights that suck the juice out of the battery
apart from this , love the van
