I was actually on my way back here with just a tiny bit of advice for the O.P.
(Not that it will help with this episode...
)
It always pays dividends to check everything out; before taking off on a trip.
Make sure that you can fill (and empty!) all of the tanks, you know how to shut off the propane to everything, and you have a practical working experience with all of the on-board systems...
(I'm sorry if the flaunting was too obvious...
)
