Hi y’all. I am going to be installing my new stackable washer and dryer and am thinking about the vent location possibilities. So far what I’ve read says best way is as short a run as possible and right out the back through the wall. So far so good… I can do that easily enough. My only major question now is when its good and freezing outside will the short vent run (about a foot) expose my dryer innards to freezing temps? Even with a backdraft damper theres just that vent flapper door between my new dryer and the cold air. Maybe install two dampers?… one inside and outside?… to kinda give the run a double insulating effect? (muck like two panes of glass) :$ thanks gentlemen for any helpful suggestions.

You're in Oklahoma, so don't worry about it. It won't ever get cold enough to give you problems.
Buy a good quality, all-metal vent cap with a weighted, adjustable damper--not one of those cheap-o plastic jobs with four or five little light-weight louvers--and install it well; worst you'll have happen is a cold draft coming out of the dryer when you open the door to load it, and that will only happen under certain barometric conditions and/or wind directions.
Here it regularly gets down to minus 40 degrees in winter--hell, it's 36 degrees Farenheit right now, in July!--; my dryer is vented with a single exit damper of the type described above and it does not create a problem.

If outside appearance isn't a big issue, forget the cheapo flapper vents and get one of those things that looks like a paint can on an elbow. (Sorry, I don't know the brand name.) They're heavy plastic, and the "valve" mechanism is plastic cap (like for plastic drain pipe) that floats in a channel inside the "paint can", settling on top of the open end of the elbow. When the thing closes it closes securely. When it's open it's wide open, with little extra resistance.
