Welcome to the forum. I am on my 2nd DRV--'05 and now '15--and the latches are a pain. I have found some help on this from others: first, if you place a small flat washer under each screw, it will distribute the pressure and may not break; second, there is a more robust hook part (part on cab door) that won't break later, can be bought hook only and it fits the latch. Have never broken one after using the larger hook--it is usually listed as a 10lb pull instead of the OEM 5lb pull.
You will need to seriously check the caulking on the bedroom slides across the bottom face plate--water will get in and rot the floor. Also can happen on the large slides...big deal, lots of chatter on several other forums.
