These things have wheels under them for a reason. Only once have I put in the slides and unhooked in the campground so I could start up and move away from a tornado storm... Interstate was close by and ran right angles to the movement of the storm. Watched it on a local TV station as it went by 10 miles away from us. Even if the campground has an underground shelter I’ll probably move before I go to the shelter.
The best weather app I have found is “Zoom weather”, cost five dollars and well worth it... picture below. Paid for itself when I was able to shoot the gap between two huge thunderstorms in Nebraska one evening...slight rain for 30 seconds. When you click on the box it expands and gives you the speed and intensity of the thunderstorms cell...2nd picture. The underlying map is as good as any Google map and I use it as a moving navigation tool.
