We have a 2018 fifth wheeler it has two TVs the rear tv in the bedroom doesn’t have as many channels as front one even in a park with cable we may have 30 plus in front and maybe 2or 3 in back same issue when on antenna are they not connected the same what am I missing
Did you have each TV re-learn the channels? That should be done each time you hook-up to a new cable service. You also need to re-learn the channels when picking-up service with the on-board antenna.

Sounds like a signal issue on the rear TV. Might be a warranty issue. If past, check the cable ends and the little wire in the center. Might re-crimp the the connector or have them replaces. Do you carry an extra coax cable for camp grounds? Try using it to bypass all the rv connects and connect it direct to make sure the TV works. It is hard to trouble shot a marginal connection.
