Bedroom TV no reception?

I have a 2011 Montana 5th wheel. First time camping in unit. We are in a campground hooked up to cable. Have TV in living room working fine. Hooked up to COACH cable inlet. I assume that means both TV's. Have tried to scan channels in Bedroom TV. Can not get anything on Bedroom TV. Have tried several times on every type of Cable type. I would think auto scan would fine any or all stations on the cable. I even went directly from another cable output directly to the Sat/Cable inlet for bedroom only. All wire seem to be hooked up. Even tried to use outside antenna on air setting. Still nothing. Is there something I am missing, switch? another cable? Any help would be appreciated.
