At the risk of telling you too much about myself. Here's my ladder project:
Buy black ladder (el cheapo).
Figure out I cant mount it the way I want.
Buy another ladder (el cheapo-only available in silver with the over the door mounts)
Sand shiney new ladder.
Paint ladder flat black.
Paint ladder with truck bed liner.
Dip mounting surfaces in liquid rubber to get gasket between van and ladder.
Paint ladder mounting hardware and screws with cold galvanizing compound.
Paint screw heads with black bed liner.
Bake all in 100 F. sun for a couple of days.
Apply two coats of wax on rear door where ladder will be mounted
Drill holes in rear door.
Coat each screw with gun grease to prevent rust.
Mount ladder.
Step back and realize that the steps in the ladder are not equally spaced. Some are crooked; some are straight. No way to adjust-pinned somehow at factory.
Looks like hell.
