Another thread here discusses whether or not it is necessary to unhook when staying only overnight. Someone mentioned emergency escapes due to weather. We had such an experience last summer.
We were going to stay at Walnut Woods State Park near Des Moines for a week while my wife attended the LWML convention there. We arrived the day before the convention began and got all set up. The next morning, while we were getting up, someone was knocking on the door - 6 a.m.! It was the park ranger telling us that everyone had to be gone by noon because the river was rising and they were afraid that there would be flooding.
Instead of a leisurely breakfast we packed up and headed out. The river was only a few inches below the road, although since it was several feet away each inch of rise amounted to a much larger volume of water. We eventually landed at Adventureland. While we were checking on our refund we found out that the water covered the power pedestals.
We had no idea that there was a possible problem, but since we aren't in the habit of putting a lot of stuff out, it didn't take us long to get ready to leave. Obviously, a tornado would have been a different story altogether, but being aware of the weather is a good idea. When we get our Airstream we'll have a somewhat different plan for departure than we do with the MH, but I'm guessing that we'll still be able to be moving in less than 30 minutes if the need arises.
