Just got my protech yesterday. I ordered it with mesh, lumber stops, and black powdercoat. This is my 3rd headache rack I have ordered from them. Outstanding quality they put in to these.
I know the older protechs had a different style gusset on the side, you had to notch the gusset to clear the tool box. They have redeisnged them, I am not sure on how well the new design works with tool boxes. I'll get some pics of how they look now.
