Sorry your having issues, but if it makes you feel any better Keystone isn't the only RV maker that seems to employ designers/engineers that appear to have no clue. Shore cords above furnace vents seem to becoming more common from what I see, and I'm beginning to think "he who uses the least amount of staples wins".
Try working on them for a month if you want real frustration.
