I'm not sure exactly what you mean by " the actual offset for our trailers is zero".
Do you mean just Bolers?

have an offset.
I forget how much.
The above idea to do this on a Boler
belongs to Robert Johans, who I guess has done quite a bit of resto work, him being in the business and all.
Here's a link to the thread.

Like I said, he didn't get any replies or post any results, so if he tried this experiment the outcome is unknown to me.
