Wow! That's a tall question. I don't think there is a piece of equipment out there that connects to the Internet that would not have down time. Satellites are plagued by atmospheric interference. Cell modems can be prone in some parts of the country to not find a connection. Camp ground WiFi services are far and few, although there are some areas where you have a pay-as-you go connection.
I have been using AT&T USB-881 modem for the past year or so. We just concluded a 4000+, 89 day, trip. Only in Millersburg, OH was there any problem with the modem's ability to connect, and in that particular instance the camp ground had free WiFi (go figure). Many times I had 1 bar, and many of those times connectivity was slow, but hey, I was connected.
I really don't think you will find a one-stop solution, but you have to research and decide what has the best connectivity for your needs. I wish I could be more helpful in a solution, but I just can't think of one.
Good luck.
Edited: I know that using libraries would mean leaving the comfort of the RV, but it is an option. Also, with a Cell Modem, it can be used as you travel, but again it will have areas that cell service is not available. With something that is portable, at least you can drive until you find a signal, stop and do your business.
