Speaking of anchors, has anyone tried those "ice angels"? It's the anchor where you drill a hole with your auger (not all the way through) and stick the anchor in the hole.
I have the clam bigfoot 4000. I only use it a few times each year. usually when I take the kids out and need extra space. really like it but the anchors suck. I bought the adapter to use the cordless drill to install them. I like Guys idea of using a bit brace. If anyone has an old one lying around collecting dust I will take it off your hands for ya...
what ever you get, make sure it is thermal.
