Forgive me if that has been asked before (i'm sure it has and this won't be the last time) but I've seen some boat trailers around lately that have what appear to be white pvc guide posts on the rear or middle. Seems to me that would really help to see the empty trailer when backing up, and help guide the boat onto the rollers straight. What's a good material to use for this, and how should the be attached?
Thanks
