Do any of you have your mirrors set exactly perpendicular to door? Rather than tilted back toward the rear of the truck in the locked position.

Funny that no one has commented? No I haven't seen anyone do it that way? for they would have to sit very far forward in the seat or not know how to use them! Going to guess that they should be set to see the last 2/3rds of the trailer? That way you have the referance point of the trailer where something is.
