You can easily figure out the ground pressure being generated by your RV....
Take the total weight, and divide by four. This will give you the average amount of that weight, that is on each foot of your jacks.
You now need to figure out the area of each pad, and divide the pounds on each Jack by that amount.
I 'll bet you a nickel and a half, that's it's a pretty large amount.
Your RV won't blow away: until you've got MANY other problems to deal with!
