I don't have the toad connected but this is what it looks like behind the MH:
This is my prototype so it's a little rough.
I used 1/2" PVC pipe on both ends with end caps.
The arrows at the front show the attachment points to stainless eyes on the MH bumper with small carabiners. You can't attach at the outside ends of the bumper because the ends of the PVC need to flex on turns.
The rear is attached directly to pre-existing holes on the arms of the towbar by stainless eyebolts through the PVC pipe and square lock pins:
The shade cloth is kept spread by self-tapping screws and washers into the PVC pipe at the ends of the sleeves.
There is a step change at the edges now because I had originally made it too long so I had to fold it back onto itself to shorten it. No it fits perfect and works well.
