I have the sides cut and the doors cut oui but because my trailer is called the BoxKite. I think my doors will be Gull wing.
But I am looking at a much different design. I am thinking of adding a ply wood peace to the outside that is making the door bigger then the opening and so when it closes it will cover the opening completely. much like a boat hatch locking the weather out.
I guess I will have to draw this and photograph it so you understand.
