July, 2011......15 miles south of Brookings, SD...............this was the only RV on its side, but add at least 7 18-wheelers to the mix too... +90 mph straight line winds from west to east with tornadoes in area. I had my WX alert radio function on and we stopped in Brookings at a Lowe's to get out of the wind and rain... good thing I heeded the WX warning, or I might have been on my side too...This was a tag trailer pulled by a SUV, and looked like they had to cut the top off the SUV to get them out....
