Allegro dash leak

[Tom T]

So I flew from Cincinnati to Portland Oregon with my friend who bought a 2014' I believe Tiffin Allegro class A, during the walk through we noticed the screws that hold the dash down by between the windshield and the vents had been monkied with some not all the way in. The salesman had no explanation! so off we went headed East down I-84, once we got to the mountains and the cold we could feel plenty of cold air coming through in that area, has anyone had issues like this? we had to keep defrost on high for 2500 miles to keep our hands from becoming numb.
