Fixing that area usually includes two major issues: First, if you decide to fix it, build yourself a dolly or rotisserie to turn the cab upside down, cutting, welding and grinding over head is a major pain, trust me. Second, even if you cut out the rust, the surrounding metal is usually too thin to weld, it'll burn right through, so you will have to cut out a way bigger part than just the rust holes. If it is not a special truck of some sort, I would shy away. I actually just got done fixing the roof of a customers truck, but it is an all original family heirloom that we wanted to keep original, but let me tell you: fixing rockers and cab corners is like a vacation in comparison!!
