Sysco - How is this STEM?

I was leaving a coffee shop and noticed this Sysco truck in the street. I noticed some type of curtain hanging in the back. I took a closer peek and it appeared to be a barrier to keep the cold air inside when the goods were being off loaded. Some of these questions might be easy, unscientific, etc but the point of STEMitizing the surroundings is to expand your vision of the world around us.

My STEM questions:

How fast does the cold air leak out when the curtain is totally closed?
Can we reinvent the curtain to make it automatically close once you exit the trailer?
How quickly does it warm up inside the truck when it is partially open?
What is the total volume of air inside the truck?
Is there a system of where they put the food inside the truck to keep the most sensitize stuff by the refrigeration unit?
