I have a 2010 Dodge Ram 1500 and earlier this past summer I was in an accident in which the other driver was at fault. There was about $7,000 worth of damages to my truck. I have filed a diminished value claim with the insurance company. How can I ensure that the amount they offer is a fair amount? The truck has been in 2 other accidents. About how much could I expect from the diminished value claim?
