Chinook RV

I opened this overhead storage compartment and apparently something was leaking in. I think a very small leak but this apparatus was right above the damp spot. I don’t know what it’s for. Does anyone? Thanks.

I don't see a picture.....

I second, no picture attached,

Wild bet says its the rooftop t.v antenna crank handle.

Is it on the driver side overhead compartment, closest to the front (behind where the thermostat is)? If there is a hand-crank, or possibly just a circle of plastic with a metal rod in the middle (missing the crank), then that would be for the outside antenna on the roof - you rotate the crank to raise and lower the antenna. If it is leaking, then you need to crank the antenna up and then go look on the roof around the antenna's base. It might need to be pulled up and reseated with butyl and/or caulking.

This is what the crank looks like with the hand-crank itself missing (just the circle and rod). Ignore the back with the wires, I was working on the wiring that runs behind the overhead compartments and had removed the back carpeted cover.

Yes!! Exactly what it is. You’re a genius. I thought the pic posted. It didn’t, Thanks so much. I had no idea there was an antennae on the roof. Just got the 98 Concourse about four or so months ago and haven’t finished exploring it all. I’ll do the fix ASAP.
