What we do is use our 22-inch TV sitting on a table under the patio awning. We always bring along two CABLE TV cables and tee them on the pedestal CABLE TV conenction using a two-port transformer. One RG cable connects to the CABLE TV port on the trailer and the second RG cable gets throwed under the trailer. Here we can connect up to the 22-inch TV sitting outside or maybe just inside your open storage bay door.
Works good for us doing it this way and always makes us put up the TV when want to leave the area unattended...
