Definitely superior. We can thank Henry Ford for square drive screws not gaining traction in the US until sometime in the 1970s.
Okay, thanks, Bruce. In your post above you said you had used the turnbuckle to pull the sidewall in, and that was throwing me. Now I understand that you used a pipe clamp to pull things together and the turnbuckle holds things together. Got it.
I recall Emery went across the coach and attached the far end of a come-along to a 2x4 on the outside of the driver's side window frame. Where were the 2 ends of your pipe clamp anchored?
