CAG1876 -
The door halves are not set up properly. As you open and close them, they should not separate (or come together). This was first discussed by Denny_A in this VERY old thread

but now the photos are gone. So after reading it, take a look at the first two photos in this thread, showing the triangle on the floor near the door.

Here's what they mean.
The upper half of the door is attached to the wall of the front shell. The lower half of the door is attached to the wall of the box, or base. If these two walls are perfectly aligned, all is well - the two halves of the door will swing as one. However, if the two walls are not perfectly aligned - if the lower wall is leaning in or out - then the doors will not swing as one unit, but will spread out as you open or close the door. This is not good, obviously. In your case, if the lower door "sags down a little bit", it means the lower wall is leaning outward. You need to pull it back to vertical.
The triangle piece in the photos is used to adjust the lower wall, to make it lean in or out until it lines up with the upper wall.
Remove the wood triangle. That uncovers a triangular metal brace. You'll see the heads of two bolts that go down through the bottom of the brace, through the floor, and terminate in big nuts under the floor of the trailer. By tightening or loosening these nuts, you can adjust the wall, leaning it in or out. These nuts are most easily adjusted by two people, one person inside the trailer to hold the bolt head to keep it from turning, and one person outside the trailer, using a wrench under the trailer to turn the nuts.
How do you know when you are done? Hold both halves of the door almost closed, but do not latch them. Look at the gap between the doors, in particular at the outer end of the gap. Now open both doors to 90 degrees. Did the gap change? If so, you have some adjusting to do. If the gap changes A LOT, then the doors will separate when you open them, which is what you are experiencing.
I
do not suggest trying to force the doors to stay together by using a big sturdy latch (handcuffs and leg irons!) If you do, the latch will force them to stay together, which means that something else has to give. I don't know what it is - but whatever it is, you don't want it to happen.
Straighten those walls! When you get them straight, your problem will go away.
