Camber is really only a tire wearing adjustment if it’s set to more than 1* in either direction. Less than 1* and camber isn’t the issue.
And 1* of camber is pretty easily visible just by looking at the tires, they will appear tipped in or out at the tops if the camber setting is over +/- 1*. So if the tires appear vertical when straight ahead, the wear issue is most likely toe. If they appear slightly tipped in or out, then it’s possible that camber is contributing. But to kill a set of tires in less than 5k miles it’s a toe setting unless there are several degrees of camber. Which would be super obvious.
I run -1.1* of camber on my duster, the camber is visible just looking at the wheels, and the increased tire wear doesn’t really show up until there’s tens of thousands of miles on the tires. And even then it’s not enough for the tires to be out of service.
