Watching the news here in Indiana, they are saying the wind is 135 mph. I think with that wind, the danger is not the trailer rocking with jacks or without jacks. The bigger danger is the entire camper flipping over and junk flying through the air, potentially punching holes and breaking out windows in the camper. Ft. Lauderdale is right in the path and you are going to get the force of it! Personally, I'd get out of Dodge.... whatever that took. Considering your's is a motorhome, (Jacks up).
And ... to respond to another poster's idea of facing the camper directly into the wind.... yes ... this is the best way. But the problem is... a hurricane is passing up the coast. Which way do you point the camper as the wind direction will be changing and shifting?
