On my 2011 327DS, the propane detector is fused (5A) in the battery compartment AFTER the shutoff relay. When power is shut off using the switch inside the coach, the propane detector and relay draw no power. Two parasitic loads I know of still exist: the leveling system and the motorized front window shade.
Unfortunately, FR didn't deem it necessary to supply instructions on how to reprogram either of these devices to the coach owner. One of the senior mechanics at my dealership didn't even know where the shade program switch was located. When power is lost to either of these devices; they "forget" their settings and won't work properly. The shade is the worst offender here, because it doesn't go all the way up and the "motor is running" setting for the shade position is lost. The coach can always be manually levelled, my preferred technique since I discovered that the automatic system doesn't do as good a job as I can with a simple carpenter's level placed on the counter at the sink.
