Very nice job, Phil!
what's your opinion on skipping the winch altogether, and just tilting the boom tip down to ground level, hooking up the truss, and tilting back up near vertical?

Great question, here's my take - but your mileage may vary:
I like the winch. It was the final piece of the puzzle allowing for exact placement of every truss where needed, without having to then go back and manually reposition them. With a boom and hook solution, to get that same result you would have to get the boom to the exact correct place in three dimensions for correct placement. With the winch, you only have to be correct in two dimensions, (N/S & E/W), but you can be well above the correct position, then use the winch to lower the truss to the correct (up/down) position. The reason I consider this beneficial is that as you are sitting trusses and get close to a wall, you start to run out of maneuvering room for the tractor. (Remember the walls in my case are already purlined, and my barn has an internal wall also.). The winch allows a steeper crane angle allowing you to work in tighter confines. In my case, I sat the 4th from the last truss from inside the building footprint, then the final three trusses were sat from outside the building by reaching over the top of the building to do so. Without the winch, I would not have had the angles required available to do this.
