i just bought the bunkboard style guide ons for my trailer, my concern is that they do not rub up on the boat itself. its like 1" away is this supposed to be normal. the directions do not show if its rubbing the boat or just close. any help would be great. p/s i read the post on the same subject here but it did not really help me. i did find that most of the iboaters like them. thank you Braxton
