OK, I started this as a reply to someone elses post but don't want to take over that post. I'm going to show my age here and probably upset people but, why do you feel the need to have TV while you are moving? Or in the bus at all? If it's to entertain kids why not just set them in front of a TV at home and not go anywhere? Isn't the point of taking trips/going/places/camping, to see and experience new things? When I was a kid and when my kids were young, we played games, talked about what we were seeing, learned how to read map etc.
A trip is an adventure. It shouldn't just be about whatever activity you have planned upon arrival. THERE ARE WINDOWS IN YOUR BUS. When I was 10 dad said we're going to Florida, here are maps for each state (gas stations maps were free and usually quite up to date), plan a route. I'm sure he checked on things but, I planned and navigated a trip from Indiana to Florida, there weren't any interstate hiways. Which brings up another point.
GET OFF THE INTERSTATES. You can't see anything. I have a million and a half miles in a truck, mostly interstate driving, but even then if there was another way to get somewhere I took state hiways, it's so much more interesting and much less boring.
My son and his wife don't have a TV in their bus either, he drives, she navigates, everyone talks to each other. We just got home from a trip, two buses, neither one of us tend to take the same route home that we used going and we both have fancy GPS units. My wife can't see a map very well anymore so my sons wife navigated. There were a lot of detours, and one small breakdown, but even with stopping for lunch and one stop at a store it still only took about 2 hours longer than the interstate route would have.
I have been married to the same lovely lady for 47 years, we still talk, and laugh (mostly at me and stupid stuff I do) I watch TV in the evenings, mostly because that's what she likes to do and I pretty much spend evenings with her. When we're in the bus in the evenings we talk, play games (I hate that) and spend time doing things with each other that we don't normally do.
The point I'm trying to make is. Use your bus/RV/camper/tent to spend time with wife/kids/friends. Kids do NOT need 100% of their time with electronic gratification. They also do not need to be entertained 100% of the time. I can't recall that my kids ever said "I'm bored" they learnde to entertain themselves by DOING things. Teach them to look out, see what is around and learn about more than what is on some little screen. I like gadgets and I have a lot of them, heck, there are 3 computers in the bus. I use them all the time to learn more about what we are seeing.
Rant basically over, although I reserve the right to add as I think of things.
