Hurrican Florence

To drive the point home, you do not want to be in an RV in a hurricane. Having been in a brick and mortar house through a half dozen or so hurricanes, about the time you realize you should not have stayed in the RV you are stuck there.
Tornadoes are what caused the most destruction in our storms, and having the truck hitched will do little to help.

I like to think I'm wiser in my old age, but maybe I'm just more cautious.
If I knew the hurricane was headed to me, I would load the camper up and go camping, about 300 miles inland.
Come back home when services have been restored, and see if you need to call the insurance company.

Having "hunkered down" thru several hurricanes, I can tell you thru experience that there is no reason for you to "live thru it ". There isn't a darn thing you can do to fix problems as they occur. So since you have to wait until the storm has passed anyway, you might as well wait where it's safe and comfortable.

After eating at the Chef and the Farmer I'd hook up and leave. If you are staying, go ahead and hook up, but don't stay in the trailer.

I would have it hooked up and ready to go if it turns out that fleeing might become an option. Full fuel in truck, full water in 5er, and pointed out the driveway.
If absolutely staying no matter what I would leave it unhooked with ALL tanks full if you have some way of draining the gray and black tanks properly after the storm passes.

I am not leaving. Should I hook trailer up to my truck for more stability?

Do you want a new fifth wheel?

These storms are hundreds of miles wide and Florence is looking to be category 3 or 4.

Don't **** around. The areas it is going to hit aren't built like they are in Florida. There is going to be massive damage.

If you want a new fifth wheel go ahead and leave it. Odds are probably decent even 60 miles in you'll see category 1 sustained at minimum, probably more and winds with gusts well into 2 and 3.

Sure it might make it. Might not. If I wanted to keep it, I wouldn't leave it.
