Had one of there drivers tear my bumper, head lights and hood off of a 2017 kw680 while I was parked in a truck stop. He took off , got at least 6 gears while accelerating. Finally he stopped when another driver got in front of him with a hammer. Said he didn't know he hit me, but he moved my truck 4 feet from where it was parked. Driver had only been driving for one week, didnt have any permits or proof of insurance. Tried to file a claim with Ozark for me having to stay in a hotel while my truck is getting fixed to get reimbursed. They say it's not there fault and will not pay. That I should have been parked somewhere else, even though I was in a marked parking spot, and the driver was cited for hit and run and leavening the site of a accident.
