Bassman did your coach come with a 160 amp or 225 amp. BIM (Battery isolation Manager)? if you have a BIM connection it automatically regulates the charge between the house batteries (WET, AGM, GEL). You should not need any additional cutoff switch the BIM takes care of that. If you have an emergency start switch on your dash it is connected to a BIM. Read the BIM manual or download it on line.
I have added an attachment if you do have this type of BIM. Happy camping.
