I would think too, the cord should be long enough to reach the plug in that location.
They typically put them in the left rear corner so you can reach over/around the open tailgate and insert the plug before closing the gate. If you are a short person, you may not be able to reach the connector if mounted forward of the hitch from either the rear or over the bed rail, unless you have fold out bed steps, running boards or something to stand on.
