Buying a TT, Bunk "Room" vs Bathroom door to outside

For me, a 2nd bathroom in a camper is wasted space. We are camping, for crying out loud...but then again, I don't even have a 2nd bath in my house. So I'm used to sharing with my wife and 3 daughters. Those 2nd baths are usually extremely small to the point of being barely useable. And then there are the inconveniences mentioned above about dumping and locked doors, etc. Personally, I'd rather have that space for the bunk room or a storage closet.
