If you lose air, your parking brake will automatically come on when the air pressure gets somewhere below 60psi, locking you in place. The air valves are for the tow truck so the truck can air up your air system and release the parking brake. This all assumes an air brake system.

If this coach is on a P30/32 chassis, those valves are probably to fill the air bags in the front coil springs. This chassis used the air bags to assist the coil springs.

Uhhhh... I'd be tempted to put some air in and see what happens, slowly of course... put an air pressure gage on to see if there is any pressure. A safer approach would be to follow the pressure lines and see where they go.

it has the tandem air ride rear wheels but i thought it had its own pump.
