Almost the same thing happened to a coworker. He had a f350 that set in his driveway that he used for pulling his camper. One day he noticed a huge dent in the side of his truck and could not figure out where the dent had come from. Thought it was his wife at first that she had hit it but she said she had not drove the vehicle. Then a few days later his neighbor was outback and said did you see that deer hit your truck? The neighbor said he was outside and noticed deer in this front yard and something spooked them and when they ran off one of the deer ran right into the side of his truck.
