Thank you all so much for all your advice and guidance. We are now the proud owners of a 2012 - 30' Classic Limited.
As we all know, anything that can go wrong will....and on our first night sleeping in our airstream - at 4AM the propane sensor goes off - scaring the living daylights out of our dog, Lucy.
After watching all the youtube we could find (at 4 AM) , it turns out these sensors only last 7 years and woohoo - it's 2019........so we were not being poisoned. There was nothing we could do in that moment, but cut it out so we could all go back to sleep. We knew were safe as long as the propane was off.
After buying a new propane detector and rewiring as it was, we are getting no power to the sensor. After finding the 12 volt
panel to see if any of the circuits needed to be reset - this didn't help, but in addition, we have lost power to the 12 volt
outlet next to the stereo. HELP please.......
