carfax for truck campers

Carfax is mostly useless anyway so if they are looking for one they drank the coolaid. I had a truck that had been in three accidents, all reported to insurance and police. The guy that bought it from me told me I must be mistaken about the accidents as carfax said it was never in an accident. Showed him pictures just to make sure he knew the true history. Checked carfax myself and it had no record of any accidents for my truck. He bought the truck based on the carfax report and dismissed my history as unreliable.
Worked fine for me as I was getting 80% of the original price ten years and 200k miles later.
