What's that coax jack for?

Sorry, I missed the part about wanting to add DirecTV. Assuming you are talking about a portable ground mounted unit there is an easy modification that will allow you to use the cable connection outside.
You remove that wall plate and locate the coax that is connected to the Cable port. Disconnect that cable and connect it to the Input side of an A/B switch. Run a new short coax from the A port right back to the wall plate where you disconnected the cable and connect a coax to the B port that runs to your satellite receiver. When you want to watch OTA TV you push the power button to on and if you want satellite or cable you push the power button to off and use the A/B switch to make a selection. If you don't forsee ever needing park Cable (like me!) you just disconnect the cable connection and run it directly to the satellite TV receiver.
There are a few trailer/5th wheel manufacturers who utilize splitters for the Cable connection sending the signal to various locations in the coach. If yours is wired that way then this will not work as you will only get 1/2 your channels and a new dedicated coax will need to be run.

Got 'er done almost exactly like you suggested. Instead of an A/B switch I used an old splitter I had lying around. I removed the cable from the "cable" side of the Cable/Antenna switch to the input side of the splitter. Then I ran one cable to the DirecTV receiver, and the other back to the Cable side of the switch.

And it works! At least at the house it allows me to watch TV from the antenna on any of the three TVs, and DirecTV on the living room TV. We won't know about park cable until we actually try it at a park, but about that only time that happens is when our view to the satellite is completely blocked.

I'm actually sort of amazed it didn't require the A/B switch, but for now, the splitter is working.

Thanks again for the input.
