I unpacked and installed the cover. It is a 36-38 ft. cover I received with a hole on each side of the cover. They were located in the same place ( height and distant) on opposite sides of the motor home. I would say Its impossible to accidently make a hole in the same place on opposite sides during installation. National covers has denied me a return or replacement, nothing more than a patch kit or 10% off on another cover @ $599.00. Stay away from this company. It's a rip off
