We've been camping every weekend to take advantage of the fall weather and our new TT.
If we are heading out the next weekend, when we get home I just plug into shore power to run the fridge and turn the battery disconnect off.
Did this with our 5th wheel for about 7 years with no ill effects.
While towing I turn it on and also top off occasionally with an auto charger.
Plan to get a battery tender for winter storage so I don't have to remember to charge it occasionally though.
