One of the weaknesses of these cabs is the square shape of the rear section. No doubt years of neglect in the open air weakens the timber and screws but the design itself is flawed. There is no strength in the B pillar so every time you shut the door you are weakening the rear section. I have seen some interesting re-enforcing and bracing of these cabs but I designed mine to be a little more discreet. On top of the rear panel is a timber strip for fixing the canvas canopy to (tacked on). I welded up a 30mm x 5mm steel strip to place under the wood and made my timber strip 5mm thinner. This strengthens the corners without being obvious. A wipe of mastic helps hide the steel. Once painted and with canvas in place it is not apparent.
