Headache racks are a must to protect the back window when throwing wood into your truck.
User preference IMHO, stock trucks don't have the window covered and I don't bust those out when I load stuff in. I put the flatbed order in for my truck and I'm going with a short headboard that ends below the window same as stock so the access between the slider windows on the truck/camper isn't blocked. Plus I don't like the looks of them.
Cool epxo pics. Lets see those completed steps too!
