I'm still kicking myself over not having a camera with me the time I was at the lumber yard and parked next to a restored 1950s pickup with a custom-made stainless steel rack on it. This marine grade aluminum rack is just as cool as that one, but it has something more - arms that fold down to support a sheet-metal brake. It's a clever design and I like the video.
Ken Morton is a local roofer here in South Jersey. He does a great business. I believe that he has his ladder racks built by a boat builder during slow periods. The racks are incredible.
