So, I've been using this system for the past month on this month long 3,500 mile trip and I have some comments about it.
The handiest part of the system is the Go2 Router with USB tethering. We've been staying in RV Parks with free wifi OR in State Parks without any Wifi. When the park has decent wifi with plenty of access points the big powered antenna on the roof isn't much use - and many times it creates problems because it's so powerful.
For instance, we spent 2-weeks at a park outside Washington DC and they had good wifi and the park's access point was about 20 feet away. I was having the devil of a time getting the system to work reliably until I unplugged the 2-mile powered antenna on the roof.
Then I just used the Go2 routers built in antenna to pick up the park's wifi and broadcast it in our RV.
And, in the State Parks without wifi, the 2-mile antenna couldn't find any wifi except the broadband cards of the other campers - and they are always password protected. So, the Go2 just used my broadband aircard that is attached to the Go2 with a USB cable.
If you boondock a lot, and park at Walmart etc, the powered roof top antenna's massive range could be a real help - but if not I'd suggest getting their cheaper $350 "Mini" system that includes a rooftop antenna that only reaches .5 mile and has a smaller indoor router with all the same features.
We've been able to use this system to watch Netflix, a little. Mostly there are halts and stalls and it's frustrating.
But we've had excellent internet access.
Without this system, when you go to a new RV park you have to log on to the parks wifi separately on all of your devices - phones, tablets, and computers. And as you move from one RV Park to another you have to log all of these devices on separately.
But with this system, you set up the Go2 router with one network id and password. Then you set up all your devices to use those settings. Then you never have to do that again. The only thing you do when you get to a new RV Park is enter the RV Parks wifi settings into the Go2 and you're done. So, for us instead of setting 5 or more devices at each RV Park. We only have to do it once on the Go2.
