My brother in law is an over the road driver. He drives the big rigs ... 18 wheelers. After hearing some of my experiences with dash cameras in my own cars, he's expressed interest in one for his truck. Are there good models I can suggest that he might consider? Most brands I've seen are focused on the car market. He said what he's seen in various truck stops are Garmin, Eagle Eye and Cobra brands, but not a huge selection to pick from. Thanks
