I don't have experience with trucks, but on buggies I would say it's usually good to start out with 0 toe-in/out up front and 1 to 2 degrees of negative camber (front and rear) - So if it's off, check (just to be sure) whether you used the right type of ball cups, the right link positions, etc. If that's all correct, just make sure you get the camber and front toe angles in a neutral range
