Well, had the hangers when I did the first post so I went ahead and used them, they have a white plastic coating so that should help keep rust away. Only change to original idea was there is no inside on most of the screws (meaning there is no wheel well to screw other end into) so I simply put the inside loop directly inside the back of the fender and used each screw to go through the outside (with a small washer) through the fender, through the inside hanger loop and then into the hole in the trailer. Did that to each fender screw and tightened it all up and it seems nice and sturdy, hardly any flex at all. Trip to Colorado coming up Wednesday so we'll see how it does.
