Do you lock your rv doors at campgrounds? Seems there are 2 schools of thought. Lock or don't lock if you are away. Some people with pets worry that if they are away and the a/c stops or there is a power outage, someone can let their pets out if the door is unlocked. I generally lock. I always lock in large campgrounds, like myrtle beach. I generally lock as i have a firearm inside. Firearms are probably another topic.
