Ok, I have avoided this thread cause I don't like the taste of Booze and beer does nothing for me (Though the taste is .. Well not as bad) so WATER is my choice.
But the general rule is your Motor home is divided into two parts.. Cockpit and "House" Keep it out of the cockpit and for sure OUT OF THE DRIVER.
I keep two bottles of wine (used for cooking) in a locked cabnet oh, perhaps 20 feet or so into the HOUSE area.
Oh, why is cabinet locked (when I'm driving) Well let's just say the factory latches are not all that good at keeping the door closed so I added a after-market lock. In fact. that is the reason.
