That crack in the ceiling is somewhat common, due to brutal punishment of the shell.
There are 2 causes.
1. Unbalanced running gear.
2. Axles that are no longer serviceable due to the failure of the rubber rods.
The fix is not difficult.
The trailer has to be suspended from the bumper to the coupler. That will allow a little gap at the top of those bulkheads. Add a plate to hide the cracks. Cut off about a 1/8 to 1/4 inch of the top of the bulkheads.
Note how much the tires dropped when the trailer was elevated. They should drop about 3 inches. If not, the rubber rods have solidified.
Then lower the trailer back on to the ground.
Next, replace the axle if necessary, and two, balance the complete running gear, or install Centramatic balancers.
