Just so you know, you need to keep about 1/3 of those tanks full with the tank heaters on or you run the risk of melting the tanks. I had a yeti equipped big horn, and landmark and found it to be really of no use for me. Again only the fresh water line from the tank to the camper is protected, but none of the other water runs are. If you have the water "on" it of course will be fine, as it will be running at around 140 degrees on its own.
