the Salem line is an entry-level line and therefore, they make things like the tv/cable hookups an option. it's very common in the RV industry.
i seem to remember a recent post on a Wildwood trailer that had the same issue. it wasn't ordered from the factory with it.
look on your invoice and it should list that as being on your trailer. if it's not listed, then you probably don't have it.
also, if you have a crank-up tv antenna on the roof, then you have the tv/cable option.
our hookups are not like the pic shown, they're under a rectangular plastic hinged flap.
