I have a 2003 model 1950 tent trailer which I bought new. After about 5 years I began noticing the door latch was farther out on the catch plate than it used to be. I then noticed as it got older it was moving farther out and to the point that when anyone got on the front bed the door would pop open if the upper plastic "hold" latch wasn't in use. I see there is a huge gap now between the door center and the frame which has to be moved out an excessive amount to put the door into position during set up. The picture shows this gap. The door does not always open/close very smoothly either. Anyone have this same problem and know what may be the cause?? Fix?
