Thanks, Paul. I looked up my weights on the Andersen website, but didn't understand that their number included the WD shank. This evening I did what I should have at the first, put the parts on a scale and my numbers were very close to yours. So the weight advantage over my previous system is even greater. I realize that there are other hitches that work differently from what I had that might be lighter.
I'm glad for this forum. It should be helpful when I eventually go to replace my hitch's lining. I guess it is like a brake shoe and does require maintenance.
