Not sure but one bade n was in 2011, I think, in Coldwater Michigan. tornadoes sighted headed for the campground. None hit but power was cut.
It poured buckets, so much so we brought the slides in. The coach rocked much of the night. The soil there is sandy so there was no standing water. The chain of lakes was noticeably higher.
This past May, in NC we had a gully washer. They went around telling everyone of the approaching storm. Slides in and really heavy rain all night. No leaks but many others had them. Coach was scrubbed clean, including wheels since we were sitting on pavement. Several that had been warned to move off lower level and soft ground didn't and stayed a while longer. One of two had to be pulled out.
On the way west near Joplin Mo we hit a gully washer, while on the road. We could not see a thing and were crawling. Wipers had no effect. All the dirt and rock dust from around St Louis was thoroughly blasted out from under.
In Tx and Oklahoma and Kansas in 2010 we had constant very high winds on our left side. We drove, in Tx mostly on the shoulder. When opposing traffic came along they went to the shoulder especially semis. In Oklahoma it was narrow Interstate with reduced speed fifty fife as compared to 75 on wide country roads in Texas. Our slide awning repeatedly unfurled. The Dealer when they repaired it after they wrecked it left the metal cover off the awning and we haven't been able to find another one.
In Arizona in 12 east, of Kingman, we had lots of rain, then snow and then dust storm to turn it into brick.
West on I40 outside, of one,of them towns we had very high winds toss semis off the opposing lanes toward us but stopped in the median. I'll thing of some more. One of them has got to be worse.
