Bill, I would not get under the front of the coach without some blocking.  If the air system were to go the coach could drop all the way down on the suspension so it you can't get under it with the air suspension all the way down, it isn't safe.  Driving up on blocks is a very good idea but if you need to still raise it on the suspension to get under it, you are still in danger.

Michael, I will definitely block it too...I'm way to chicken & fat to take any chances with the air holding the coach... Thanks for the suggestions and ideas gents.
