Whenever I dry camp I always turn the disconnect off for the engine batteries, gives me peace of mind I will for sure have full batteries to start the engine. Actually I do that even when im plugged in or whenever I am not using the engine. If the merge switch does get left on or something happens to the charger the engine batteries are isolated.
