IIRC the engine computer will have a constant draw. Does your coach have an echo charger or similar? That pulls a small amount of power from the house batteries to charge the chassis batteries. That along with other things like any phone chargers, etc. and the AquaHot basement heaters can cause a drop. These heaters' fans may run whether the aquahot is on or not.
