I can't agree that this is logical, neccessary, or practical advice. It is not like blowing a tire.
If an airbag leaks or ruptures your vehicle still has fully operational springs and shocks. You might replace the airbag at the next practical time. The airbag assists the springs and shocks, it doesn't replace them. And the tongue weight of the trailer shouldn't exceed the capacity of the vehicle even if airbags are used.
