In the event of tornado.
Best option: GET OUT OF DODGE.. There is a governmental readiness test, one of the questions is "Where is the best place to shelter in the event of a Hurricane?" the answers (Multiple guess) are "Indoors" "Outdoors" "underground" "in a shelter outside the storm area"
I've busted up laughing when I read it because I've always said "ELSEWHERE" (A shelter outside the storm area is elsewhere).
So Option one is get out of dodge
Option 2 is pull in the slides if you have the time and.... No matter if you have the time
GET YE TO THE DESIGNATED SHELTER,,
Your RV and contents: Replacable
You: NOT.
