Does your home jurisdiction require air brake endorsement?
Are there jurisdictions about the continent that allow people to drive air brake equipped vehicles without any type of training or license endorsement?

You are right, that there are auto tank drains available. I replaced several of them on commercial trucks with manual drains. They may work alright on a coach but I found after period of use they would be the source of an air leak. I much prefer the manual ones with the lanyard to pull to eliminate getting under there to drain them.
