Forget about satellite for internet - way too slow to be productive. We have a Verizon mifi with a 30gb a month plan (shared with our phones, which use none) that costs $130 a month. I don't know if they offer that plan now. Even at that, streaming video doesn't work for us - it takes up too much bandwidth. We've found a very few RV parks where the park WiFi was usable, and even one or two where it was fantastic. And in those parks, figure on paying at least $45 a month for the service. Unless you're addicted to non-broadcast TV which has to be streamed or satellite-delivered, get a decent off-air antenna and pick up the local channels in your area for free. Or stay in an RV park that offers cable TV.
