Battens

I've just about decided to go batten-less on my Truck Shop. There are lots of 'out' buildings around where I grew-up and battens seem out of place on a shop that was thrown together for function. A office or house battens--Yes because it needed to be air tight. This truck shop will never be air tight. Who cares if the truck gets cold at night. I just think that rustic is the way. I read the thread about smaller but I think none. Any reason why not to go batten-less like the building next door is already batten-less?

I'm also thinking about a sheet metal roof. I saw the thread about the tin roof. Any suggestions for who sells or how to make corrogated sheet metal roofing?

Warning - For my first model ever I'm getting pretty cocky! Don't worry I'll break something and things will be normal. Like the other day when the stained lazer-cut windows that I left by the stove caught fire--only a small one-- I lost the tarpaper shed windows and a sash.
