All well here, off to the mainland this weekend to see "Chicago" should be quite a show!
For a grill, you can't use the coach propane line which should exit on passenger side about the second storage comparment down, as it is already pressure regulated. To use coach propane for a grill you would have to plumb a second propane line from the tank, before the Low Pressure regulator (on the tank) for the grill. All grills have a pressure regulator attached. We use the onboard propane for our propane firepit and it works great, on the long weekend we will be up there and can take a pic for you. For our grill we use a napoleon travelQ and just use the disposable propane bottles. Do I have you confused yet?
