I just discovered something yesterday RE House battery cut off. To the left of the left hand battery (toward rear of coach) there is a 100amp breaker mounted on the side wall.
Our is a 25.3 but yours may be the same location. There is a blue button which, if pushed, breaks the hot side of the house batteries and isolates them. I was going to install a cut off switch but after discovering the breaker I think I will open the breaker while the RV in in storage.
