On modern equipment disconnecting the electrical source from the rig (car,truck,MH,etc) for a minimum of 30 will allow the little computers we didn't know were installed to go to sleep and reset. those reading are very high I would use a multimeter and check actual battery charge after disconnecting the leads. If there is that kind of amp draw secure systems one at a time to find the culprit Let the forum know what you find. On many MHs charging of the house batteries does not take place until the starting batter has reached full charge so running the engine to charge may take a long time.
