Help, won't open right...

I'm in the middle of a two week trip right now.

Last night, rear shell was kind of tough to get fully opened - it raises fine, but doesn't quite want to go back far enough.

Well tonight was even worse - I couldn't get the starboard side rear square aluminum latch (not sure what it's called) to latch - the rear shell simply won't go back far enough. I was able to muscle the port side one in, and I was able to get the rear bed far enough back to put the bathroom up - but barely.

I'm worried that it may have got damaged two days ago. When setting up, I noticed that the rear side main latch on the port side had come unlatched in transport. It didn't look like it broke anything, but...

It's new, and I'm sure my dealer would fix it no problem - but I'm thousands of miles away and would rather not spend time doing that if there's something quick I can do that will get me through the trip.
