Hello Johnny B: I did the same thing that Zach did, but I used 2 1/2" x 2 1/2" x 1/8" square tubing. I reused the HF coupler and it bolted right on the new extension.
I took some angle and made some attaching tabs and welded them to the extension where they meet the cross members and bolted them to the cross members with 3/8" bolts into the existing holes in the cross members.


I cut the "box" off the upper triangle plate with a cut off wheel and flipped it over and bolted the triangle plate down over the new tubing. When it was all centered up, I welded the bottom triangle to the new extension.

The portion of the box that was still attached to the upper triangle is 2 1/2" wide and it sets perfectly over the extension and holds the tube in place. That way, I can remove the extension in the future if need be for some reason. There is no side to side movement this way. The upper plate sat about 1/16" higher than the A frame. The bolts pulled it down tight as they were drawn down holding it very firmly.


By doing this modification, I moved the coupler 24 inches forward from it's original location. It turned out great and it is stronger and much easier to back the trailer now.

Welcome to TD's. You will end up building a very nice TD with the help and encouragement of the people on this forum.
P.S. I used to live in Wooster and I was born in Orrville. My sister lives in Canton.
