I generally remove mine unless towing on consecutive days, but I do so because I choose to.
This thread reminds me of the story of the man who sat on a park bench across from a little boy who was sitting there stuffing one candy bar after another into his mouth.
Man - "You know little boy, you shouldn't eat that much chocolate. It will give you acne, you'll get fat, get diabetes, and you'll die at a young age.
Little boy - "That's funny, my grandad lived to be 103 years old."
Man - "Did he typically eat six Snickers in one sitting?"
Little boy - "No, he minded his own d*mn business!"
