Do you travel with your interior doors open or shut

I've never thought of traveling with them closed. Why go to the effort (although it's not much) to close and open them all of the time? Why did you consider the question?

I asked him because the doors can be latched open or shut. My old coach could only be latched open. I've also heard of folks shutting them to reduce the air volume that needs to be cooled up front while traveling.
