I'm getting a 18'Wx26'L metal carport installed in a few weeks. They normally anchor them with 1/2" dia x 3' long rebar anchors. I think they put 4 on each side. Since I'm planning on moving it next summer, I'm considering not having them anchor it with the rebar and using sandbags to hold it in place. Will this work? If so, how many 50lb sandbags would I need?

Another option is to have them anchor it with the rebar, then pull them out when I move it. My tractor's 3pt hitch is rated to lift 1600lbs 2' aft of the hitch, so it seems like it would have enough strength to pull them out. Has anyone tried something like this?
