Saw a container home in Arizona that wasn't insulated right

I was down near Tucson last week checking out a guy's container build and he had spray foam on the inside but no vapor barrier on the outer steel. Three months in and he already has rust spots forming along the seams where moisture is getting trapped. Has anyone else dealt with condensation issues in a dry climate like that?

Actually, AZ's dry heat makes condensation worse at night since the steel cools down fast.
