2014 Exterior Door Hinge

[JandC]

Did a search on forum but didn't see anything. The exterior door on our new 3725 didn't have the little plastic holder for keeping it open back against the unit. The salesman said he thought it was some sort of new "stiff hinge" and therefore didn't need to be secured while leaving open. Today is the first really windy day we have had. Getting gusts about 30 mph so I have door opened about half way to see if it stays.....so far so good. Anyone else get a Montana in 2013 or 2014 that came like this?
