What's the one thing that you have but hardly EVER use?

We have always been minimalist RVers, as others have said we travel and camp for the night and move on, we don't sit in one place more than a day or two at most and usually not much more than 12hr. Largest camper we have ever owned was an 8.5' slide in camper, so stuff that isn't used does't go along for long. In 40+ years of camping we never had a TV. We bought a used B last June with a TV/DVD combo. I turned it on to see if it worked, DVD worked, needed to be plugged into cable for the TV to work no antenna. After the first outing we decided it would not get used much if at all, other have given the reasons. I pulled it out and found a large empty area that had no access before, so I boxed in the space and added a door and have one of our more useful storage areas since it is right by the kitchen. We tend to go on two different kinds of trips so a few things move in and out depending on the trip.

We will see after this Summer what needs to be removed or added.
