Most TVs sold today are capable of receiving three types of TV signals, NTSC, ATSC, and un-encrypted QAM (aka ClearQAM).
QAM comes in two flavors, encrypted and un-encrypted. Up until recently cable companies were required to furnish the local broadcast channels un-encrypted. Many if not most cable companies are now encrypting all channels. This means that all TVs would require a set-top box to receive cable.
I don't know how RV parks are distributing cable to it's customers. It's possible that encryption is stripped from some of the channels allowing customers to view these channels on TVs that have a QAM tuner. As TechWriter has stated, some TVs do not have a QAM tuner. A set-top box would be required if you have an old analog TV, if your TV does not have a QAM tuner, or you wish to watch all the digital channels.
- NTSC - Analog OTA (Over The Air) TV
- ATSC - Digital OTA TV
- QAM - Digital cable.
