Great job !!!!! I use one that a buddy pieced together years ago, he has since passed I have no idea how much he bought and how much he built. I have one suggestion, have you thought of adding a hand held spray wand? We have the pressure line t'd off several different ways. You can spray with one boom, both booms, either or both booms with the wand or just the wand. The hose for the wand is 20' or so long, coiled up on the rear of the tank.. you can use it from drivers seat or have some one walking behind/beside you and spray around trees, ponds .... whatever. We have even used it to put out the edges of controlled burns. I highly recommend being the one on the tractor not the guy walking LOL. I just helped a buddy burn 40 acres and I was the the youngest of the bunch
(40) so I got the hard job.
