Do you have a good AT&T signal at your home now? That would be very important since it's locked to AT&T.
I recently installed the TOGO. I'm not seeing blazing speeds, but it has been good enough to stream movies on a Roku as well as browse with other devices at the same time. The average speed seems to be about 10 Mbps. I have yet to test it anywhere but my backyard.
If your RV is somewhat close to the house and always connected to power, you could just leave it on the RV. Mine is roughly 30 feet away and I can use it in the house. Fortunately, I have AT&T fiber at home (350 Mbps!). I did connect a Roku from within my house to the TOGO and ran it for multiple days to test the performance of the TOGO. It performed well. The reach of the Wifi MIMO antennas is also impressive.
There are only two connections on the TOGO. Two wires for 12 volts input power and a hidden ethernet connection. They don't really advertise the ethernet port and the one extra hole in the TOGO is too small to simply connect a cable. You would have to run the wire into the TOGO and then install an ethernet connector.
You could then install an ethernet jack somewhere on the RV. Install a wireless router in your house. Then just run a cable from the wireless router to the RV ethernet jack. Connect all of your home devices to the wireless router. No setup required with the ethernet port. Just plug it in.
