Wireless is not a possibility due to the siding interfering with the signal. Tried that already!

I want the ethernet because it can handle the needed bandwidth for TV (Netflix etc) and my internet usage at the same time.

TW's solution is pretty much what I was thinking. I've been checking the RV stores but no one seems to have the proper (read: recessed) box for a camper. Sure, I can drill a hole and put in a grommet and seal it and even put in a weatherproof box, my concern here is packet loss over that long a run plus the connection might be noisy.

I was hoping there was a engineer-type who knows more than I do about these things. Data is not the same as electricity.
