It has to either be the gas strut ( if that was used then) or the plastic thing that hooks onto the door to keep it against the trailer. But those were screwed on ,I think. I had the strut and took it off and added the plastic thing so the door would be wide open.
It was a rainy few days at Algonquin Prov park...tarps kept us dry.
