On a level surface, what is the height from the frame to the ground in the front and the back on each side? Measure from where the frame leaves the body of the coach. What is the difference from side to side?
Simple stuff first. Tire pressure the same from side to side? Lug nuts tight?
Is the "lean" constant from front to back? If so you might jack up the street side till the tire is off the ground and see if the axle spring is working.
Where is the crack on the frame? Is any sheet AL bending or buckling along the side of the trailer?
