Can you post some pictures??
I had to remove doors to repair. First time my wife got too close to a post at fuel station and pancaked the hinge on two of the doors but surprisingly very little damage to the doors but I had to buy both pieces of the hinge system. In 2013 I was able to buy the door side piece from Monaco and had to buy a used piece that attaches to the side of the motorhome from Visione RV Salvage. Paid more for a 7' piece of the used vs a 14' piece of new. Monaco cut the 14' piece into shorter pieces to make it easier to ship.

Last time I had to remove 3 doors starting with the wet bay door.
On mine there was a rivet installed in the extrusion attached to the side of the motor home, these are to keep the doors from sliding.
I just removed one door at a time and slide them back.
The extrusions are male female type fit. I guess it's possible for either side to become deformed a little to allow the two to come apart. If you have to remove more then one door you should be able to see if there is a problem. Might be able to gently pound the lips of the pieces together a little to make a tighter fit.
