If you want free you have to find a campground that offers free wi-fi. The problem is, if you are now spoiled, the "free" wi-fi is generally pretty crappy and it may not even be available at your site. You may have to take the computer to the clubhouse or office.
If you want dependable internet service you are going to need a cellular device and the amount of data you can download will be limited, but only limited by your budget!
Free TV is going to be campground cable (limited channels and not available at all parks) or your over-the-air TV antenna like a Winegard Batwing antenna. If you want dependable TV service you are going to need to subscribe to Dish or DirecTV, get the proper RV antenna and watch whatever you like where ever you travel.
What I post is my 2 cents and nothing more. Please don't read anything into my post that's not there. If you disagree, that's OK.
Can't we all just get along?
