Just my opinion riding out the storm could work depending on how strong it is when it gets to where you are. As others have said consider staying at a safer structure during the storm.
If you are in a park with trees they can be your friend and protect you from the wind but they could be what falls and damage coach.
You have an advantage over others in that your in a MOTOR HOME I would think you could find someone to get you hooked up so you could leave area for a few days then return for your treatment assuming you can drive your rig.
I live in North central Fl. I could head your way and help in anyway you would need including driving your rig. Let me know wife and I will jump in car and head your way.
