the bars are the easy part
I would get a good sized hinge and put it on the other end of the hut in the middle and drill a hole in it the same size as the hole in the bar, stick the pin in it and you have instant hitch
well the law is all would need to be attached with a rigid tow-bar
now if you could tie the huts together so close that there is no side to side movement, I would call that rigid
I love old pictures
I thought I would try to fix one up
but in the end I think they look better in their original condition
