I don't think the bulkhead changed length, so what is happening is the ceiling is now closer to the floor.
How can that happen? The most likely answer is that the walls of the shell are not being properly supported by the plywood floor and/or the frame out riggers are no longer supporting the floor. Either or both conditions will permit the shell to drop resulting in what you have observed.
Deterioration of floor and out riggers seems to go hand in hand and is unfortunately all too common on older units, especially if they were stored outside or lived in full time. The root cause is moisture damage from leaks or condensation which rots the floor and rusts out the out riggers.
A consultation with someone in your area who has dealt with floor/out rigger replacement might be worth your time if you are still considering purchasing this trailer.
