I added a outside satellite/cable out for my 19fbpr. This will allow me to watch TV outside. For convenience I installed the cable outlet on the left side of the RV near the power cord outlet. This was the best location for running the coax to the TV. I will just have to run the coax under the trailer to the right side of the RV when in use.
I have Dish Satellite with a portable Tailgater dish. I use the 211k receiver which has a Satellite Out jack on the back of the receiver, so it's just a matter of connection to the wall outlet.
