Really cool Jamie.
Second on the gussets.
I like the width, if you have the space. Under 36"?
Once you (the boss) sees how much work it saves, especially on downhills and flats, maybe the boss will see the need for a light duty, and a heavy duty. I put a madrone (our densest wood, probably 5k/ green cord) log on the AT at the end with the boxer, and the other end in the grapple. It was NOT light. AT didn't care, really. I cut the log to load it one end at a time, as I couldn't make a turn with it- about 16 feet long.
With light brush and flat ground, you can extend up the sides, too.
