Not sure why you're having the problem you state.
Are we to assume you CAN see down the driver side okay?
Are we to assume the mirrors extend the same distance out from the tow vehicle on both sides?
Just exactly what is the width of the trailer?
What is the distance the mirrors stick out?
The trailer hitch IS dead center on the tow vehicle?
