CVA-64!! I owned 3 older rigs that didn't have the LPG detector and never worried about it. Bought a Minney-Winney new in 1994 and discovered if the rig was not used for a couple of weeks the hardwired LPG detector would kill the coach battery. So I wired in an on/off switch. Then the detector kept going off and so the switch remained OFF for several years. Likewise the detector in my current rig was killing the batteries when the rig was not used so I added an on/off switch. After a year or so the dectector became overly sensitive and the switch is in the off mode and has been in that mode for years. Problem solved.
