Don't confuse the satellite TV receiver (Wally) with anything having to do with cable. For campground cable you just connect a length of coax from the campground power pole connection to the RV input cable connection (not the ones in the bays where a TV is expected to be). You then turn OFF the OTA TV antenna power supply (small wall plate with push button or slide switch and a tiny light) and this allows cable to go to the TV's instead of OTA. Change the TV input from Antenna to Cable and do a new channel scan.
The satellite TV and your Pathway X2 cannot use the same cable input connection without some wiring modifications so how that setup works will be a separate discussion. Has someone ever used satellite TV in that RV?
