Exterior door problems

[Garyaero]

I have a older 24' Terry trailer and the exterior door is uneven while the frame is even. Across the top from the hinge side (where it ok) to the strike there is 3/4 in difference. And the strike side from top to bottom there is only 1/16 inch difference. The frame is perfectly square. Any idea whats causing it. Is there a way to attach pictures I could do that so you could see it

Had a class C with a sagged door. Took it off, took the outside metal trim off and the hinge side wooden support was rotted through. Did not look that tough to replace, but I fixed by trading it on TT Dave

You don't have it setting on the leveling jacks do you? Having the jacks too high can cause the doors to be off.

In what dimension is the 3/4" difference? If the frame is square and there is no more than 1/16" difference along the strike side, I can't picture the door having that much of a top side difference in 24"-28".
