We recently had to replace both the engine and coach batteries on our RV. There is a button on the door for battery use or store. What is that button supposed to be on? We’re newbies to the big RV.

Welcome to the wonderful world of RVing! This switch is commonly called the Battery Disconnect Switch and is designed to disconnect your house batteries while being stored.
Pushing it to the Storage side is like taking off the battery cable. It ensures that if you have left a light on in a compartment or anything inside, it will not drain your house batteries. Some RV manufacturers connect the LP Leak Detector directly to the battery bypassing the disconnect, so you may still have a draw even with the switch on Storage.
To find out if this is the case with your rig, get a 12-volt test light, push the switch to Storage, then disconnect the negative terminal on one of the batteries. Touch the probe to the post and the alligator clip to the cable. If the light comes on, you have a draw.
