Yes it would.
You switch the cable lead at the roof antenna control box so you cable lead goes thru the satellite receiver and the signal out from the satellite receiver goes in at the roof controller at that point you have the signal from the satellite receiver to all TV’s. You can only watch the same satellite program on all TV’s. You must turn off the roof antenna booster.
This is a post that has the diagram for your trailer. It is the one on the bottom of the list.
You can see that the cable coax feeds thru the roof antenna control box to all TV’s.
