On the edge of the door there is a plastic cap that can be popped off revealing an adjustment screw or bolt (My recollection is fuzzy). Anyway you can make small incremental changes that control the latching. Be very careful as you actually can adjust it such the door will not unlatch or even latch when adjusted too much the other direction.
Hint...from experience of being locked out of our motorhome, I now always leave a window unlocked and open when working the entry door!! My wife has photos of me climbing through the window as a reminder of the experience.
