Are the latches actually stuck or is it the doors themselves? If it is the doors, are you on a level site? I have seen where coaches that are not level causing the chassis to "twist" somewhat causing side-swinging doors to stick. It may not even look that far off, but if the top clearance is tight it doesn't take much to jam the doors.
Sometimes the door hinges need to be adjusted down to create more clearance at the top edge.
