I have the Berkshire 36, in the basement area there are two connections for air hoses. I take it we can use those connections to air up the tires? If so does the coach have to be on while doing this?
I would check to make sure that they are the air hose connectors. Unless your coach is radically different than mine, the air hose connection is on the fire wall in front of the driver and the connections in the basement are for hooking up to the propane tank.
