Internet based TV only works where you have a good connection to the internet. There's many places were you would be disappointed.

BTW, a strong Wi-Fi signal has no relationship to a good internet connection. A good Wi-Fi signal simply means you can connect to the Wi-Fi base station well.

Also keep in mind that a RV park has no obligation to carry video streaming services over their free Wi-Fi service. They can easily block or throttle back those services. So, make sure you have a great data plan with your carrier.
