Nice work Sir as always,
I'll confess a set of instructions would be useful for some of the range.(some of the new models will need them).I did take a couple of pictures of it in resin and white metal to help with placing until I can catch up with line Drawings.
Your right the supports are longer than most common version of the roof. For two reasons,it can be adjusted to cover most hight variations (I found so many variations all claiming to be the same Mark/model of vehicle)without the need additional parts.Also you can add the canvas rolls on the sides and still see the interior detail.Also the whole thing can be built without the roof without the need to fill any holes for roof supports. I think I mentioned this in the sneaky peak thread.If I did sorry for repeating myself.
I wish you post a few of the pictures from your blog as well its nice to see how you use it conjunction with other models in your collection.

Mark.
