Disconnect starting and house battery

I have few questions regarding which battery to disconnect in the following scenarios:



1- I am replacing the starting battery on my Ford F-53, should I just shut off / disconnect the starting battery? Or disconnect house batteries too ?

2-I want to spray battery terminal rust protector on both chassis and house batteries, should I disconnect both in the this case ?

3- I want to start the RV (while in place without moving it) , should I disconnect the house batteries ? or just turn off the RV Park electric box ?



Thank you
