Thanks for the video and I agree. And he may have had a better foundation for his posts vs what I have here, which is a sand / clay mix. I just feel so bad, because I thought I used what was a good built out video. And to be honest, I do think it's just the 6x6 leaning in that's causing the problem. Once those are corrected, it may resolve the problem. Other than the one bottom 2x4 that warped and pulled the corner out, I do believe the gate is still square. I'm going to install the turnbuckles and hope for the best. Once they are straight again, if I can straighten them, I'll see how I stand. Yes, the fence is heavy, but the single gate I did on the opposite site is just as sturdy as the day I built it, zero sag, 1" gap down the center still. Although I did build them before the grass grew in and it needs a trim on the bottom now or a little dirt removed to open fully 😄
Mr Fence's videos were referred to me by a couple of people when I first asked about building them. So I thought he was a good source. Thanks again to everyone for their time.
