I think our sister coaches are similar...
a couple of ways to adjust either the latch loop
or the door itself...
first find out what is wrong... is the latch loop out of alignment or the door swing?
either crawl in the basement with a flashlight and close the door so you can watch it close
or mark up the latch loop/lock area with something that will show you where it meets when closing...
On mine, the latch loop (on the chassis that the door latches to) can be moved all for directions by loosening the bolts...
the door swing can be adjusted by SLIGHTLY loosening the hinge bolts and tweaking the door...
be careful because that movement will make the 'lines' of the door out of alignment with the other doors and/or make it hit the other door...
here's a bad pic of the latch loop:
