Yes Walt, fix it before driving it. The air-brake system is allowed to lose 5psi every 2minutes, more than that is not legal.
You likely have a leaky air-bag or leveling valve. Block the coach up so that it doesn't lower on you, pressurize the air system (preferrably using an outside air source), and crawl around looking for leaks.
Air bags are much cheaper from a truck parts dealer than through BlueBird.
