What are these?

Obviously, the first picture is of a devining rod, used to find water at a campground. You put one handle in each hand, walk around the RV, until you see a spigot near the power box, and you have found your water:B

I think it could also be used for a sewage tank dolly.....but that is just a guess:B

Second picture looks like a headphone jack....maybe they have it set up for folks that want to listen to music when they go to bed, but don't want to disturb the other folks in the camper, or the CG.?
