I decided to use trunking for my house/window/roof and gutter lines. I find it very easy to drill using my homemade jig and no need to worry about the "twist" you can get with conduit.
So I found a way to move my portable hole around (thank god!)
Using a hand trolley I ratchet up off the front tie downs to slip the trolley plate underneath.
Then ratchet the back taught to lever it up and roll it around, still friggin heavy!
