thanks for responses. I turn very slowly because I see that when I turn it looks like he gets offbalance. I padded the door similar to the one in picture. I hauled for 3 hrs yesterday and he did not scrape up again, but I could see him leaning and unbalanced when I turn to right. I will go out and measure my trailer.
If head tie down and butt bar are good then that's all that I can think of without more information.
I'll wait for that and others to suggest things.
