Had a parasitic draw on my old Ford Expedition. It took ages to track it down, but it turned out that the rear windscreen wiper would occasionally seize in the non-parked position, and the motor would just keep driving trying to push it to the parked spot.

Even after I fixed it I had to replace the battery - as it was damaged.
