About the problem of the truss's lifting off the wall's. I have this in my house and it's driving me nuts. I've read you answer as to why it's happening. Now, what would happen if you were to bolt down the truss to the wall, say with a heavy gauge "L" bracket. Lag it into the side of the truss, then use a long lag into the top plate of the wall. DO you think this would do any good , or do you think it would just pull up the top plate with it?
Thanks for any help, Rex
