I posted earlier, on a different page, but having just finished setting this up I felt the need to repost.
The wind gusts last night were powerful enough to swivel my camper nearly 30 degrees. This was done with me inside, all 196 lbs of me, all my gear, both dogs, and with the camper sitting down on both blocks and all four (4) jack legs. It took me nearly an hour to rotate it back using a very large lever after I pulled the legs up. Then had to reset them - I suppose the camper would have been toppled instead if the legs had not been extended for added support.
