The parasitic losses in most coaches are the rear radio's memory and usually the carbon monoxide/propane monitor. Most of the reason for a discharged house battery is self discharge and poor maintenance. A three year old FLA battery well used will self discharge at 0.8 to 1.2% per day. In 60 days it will be effectively total discharged. The longer a LFA remains partially discharged greatly effects battery life. You can look at the battery post of the latching relay as see what wires bypass the use/store - master power switch.
