Are you aware that a car parked isn't at all the same scenario? It is not like remodeling an RV is going to affect the gas tank. But it sure will make a difference to the battery usage. A gas tank doesn't age in the same way as a battery either, and we don't have as much experience with the kind of battery packs used in cars either (and they differ wildly between models).
