I ended up buying a 16' trailer with a 2' dovetail. I'm not sure what the width was, and the trailer has since been stolen so I can't check, but I think the widths are pretty standard. The one I bought had 2 3500 LB axles, so it could haul about 5500 LBS. I think I remember the GP weighed about 4200 LBS.
Let me know if I can answer any more questions.

Dave,
I ran across your post about trailering your 67 GP. I've got to pick up a 67 GP that I purchased. What did you wind up using for a trailer, size-wise? Length, width?
Thanks
Rick
