Right now, I've mounted the mini in the RV's roof vent. I didn't have time to mount it to the roof before we left on vacation. Going down the road, we have streaming TV and all the internet service we need.
I've had a bit of a dilemma with it, though. Part of RVing and offroading is getting away from phones/tech. That said, when the freaking 18-wheeler in front of you drops scrap metal all over the highway that eats an RV tire, 2 trailer tires, and there is no cell service, it was a godsend.
