My 6.0 and ARC weathered Ivan snugged up in the backyard. They moved around some, but survived with no damage. The trailer anchors work well too. Get the longest ones you can if you go that route. I use a couple of 5 foot long ones to anchor the ARC on the beach -- when these freakin' storms aren't around. $#@&%
