Dometic RM1350 left refridge door flapper problem

I hear you,but there is no play on the top hinge. nowhere for the door to go up. It looks like someone has inserted washers on the lower hinge like you suggested. I bought this 2016 Keystone avalanche last year but don't know the history of the fridge. Someone has tinkered with it.
I need to raise the flapper which may not be feasible or lower the part that the flapper is to ride in. That I think I can do.
