Harry is right. In the RV you have lots of little Amp Eaters that are sucking from the battery 7*24.
Just too clarify, I think you said Chassis battery? You also have Amp Eaters sucking on you chassis battery even when you think the vehicle is 'off'. Typically this can be as high as 50Milliapms so you sound like you doing really well. The radio memory for example pulls some current even when the radio is off. You have others too. If you want to test the emergency start function that joins the house and chassis battery together (I think this is what you are asking to do) then get the house fully charged. Measure the volts on each battery set and note the voltages. Keep your ignition off or in just the auxiliary position and turn your head lights on to pull the chassis battery voltage down below the house battery by a few tenths of a volt. Not so low you can start the engine! Now, press the emergency start and if the two battery systems join together to 'jump the chassis battery' you will see a jump in the chassis battery voltage. If it stays the same, your not getting the circuits bridged. May need somebody to help you so you can stay 'eyes on' the volt meter while a helping hand flicks switches. Personally I try to not leave home without a volt meter and the DW!
