Satellite TV plug on the roof
I was up on the roof yesterday doing a better job sealing the running lights on my month old motorhome - although it was built in February - after reading some horror stories about them being a source for water leaking into the overhead bunk. While I was up there I noticed tucked under the front edge of the A/C unit is what appears to be a cable TV jack built into the roof. I'm assuming this is a connection for a satellite dish cable.
I don't ever plan on adding a satellite dish to my motorhome so I'm really not interested in using it. I am concerned though as it has a rubber cap covering it. I'm worried about the cap coming off without me noticing it and water infiltrating through the cable jack. Is that even possible, can water enter through a cable jack? I gave half a thought of covering the whole thing with some lap sealant but I don't want to ruin the connector in the event I ever sell the camper.
