Forget the shutoff valve. Just disconnect the hose to the bag and install a schrader. Then air it up to the required clearance. Measure the pressure. Once that is done, make a sign and tape it to the sides of the coach over the rear wheels. Make the sign bi-lingual. On each side it should say "Rear Air Suspension." "If the vehicle is low, inflate here (with an arrow pointing inside) to xxx PSI BEFORE moving the vehicle." You could even pack a cheap 12 volt air compressor inside the coach.

If a bag were to blow, it would be no different than a tire blowing. You will have to fix it. You could throw a Ragusa bag eliminator or spare bag (with instructions) inside of the coach if it really bothers you.

I really think we are making more out of this than necessary. Lots of things could go wrong on any vehicle being transported but we do not pack extra parts for all of those possible failures. This is not the first time a GMC has been put on a ship.

Ken,

You've got a point; Jake could just install a shutoff valve and Schrader valve at the bag inlet and inflate the bags with enough
pressure to get the 14" ground clearance and then shut them off. I assume the 14" inch clearance is because a GMC is a roll on roll
off shipment.

My concerns would be:

1) how much pressure would have to be applied to the bags to raise his GMC enough to meet the 14" ground clearance.

2) the length of time the air bags would be at that pressure.

3) if an air bag did bleed down would anyone on the ship or on the docks when it arrived in Finland know how to air them back up?

4) if an air bag were to blow in transit how would it be repaired on the ship?
