John, Thanks for your quick response and the picture showing the vent location. It is located much higher, which is good, than what I was expecting. If it is not to much of a problem, can provide some dimensions of the center of the vent in relationship to the front and bottom of
the overhang. Example, measuring from the center of vent along the flat side of the trailer to the nearest obstructions, top and bottom.
Thanks again for your help. Regards, Jim
