I wouldn't believe this one... parked car hit me!

Actually you were both at fault. There is no such thing as an "accident" unless while you are driving down the road a tree limb falls and hits your vehicle. You did not experience an "accident" you experienced a "crash".

If after he cleared your TV on such a narrow road should you have maybe stopped to make sure he made it all the way past your trailer? YES

If when he was trying to drive around you on a narrow 12' road should he have pulled more out of the way or started sounding his horn? YES
