Living in RV heaven. You think cars are bad!
On my wife's '02 Caravan, sometimes when she shuts it down the daytime running lights stay on. At least that's what I suspect as the tail lights aren't on. She always drives with lights on so I figure when she turns the lights out, the drl come on and maybe the relay is sticking. Sometimes if you turn the headlights on & off a couple times with key off, they go out. When you let them go on their own it may take 30-45 seconds or longer but so far, they've always went out.
