My garage is detached, however, it is less than 10′ from my house. Because of this, I had to build it to certain specs, gfci outlets and sheetrock were the main two. I’m just hanging the rock and am getting ready to fire tape it. I plan on giving it two coats of “mud” then prime and paint it so it looks decent. My quesiton is, the garage will not be heated all the time. I live in northern wisconsin, some nights this winter were -40. Will the “mud” hold up to these type of temperatures? I’m concerned about it cracking, and i wouldn’t mind if it did a little, but I hate to go through all of the work and have it look terrible. Any products out there for these type of situations?

It should be fine unless there is moisture in it. Keep moisture out of it and it will be fine.
How would I keep moisture out of it??? Our summers are really humid, so I'm guessing it will suck up a lot of moisture. Is there any type of paint, (such as exterior paint??) that I could apply to it to keep most of the moisture from penetrating it?

The moisture will leave as the humidity goes down. The lag time is only a couple of days.
This is the kind of question which is probably better answered by your local drywall supplier. Local knowledge often trumps message board advice, particularly when extreme conditions are involved.
I don't think it is a problem but you could ask a local supplier like Hudson Valley Framer suggested.
any other insights or suggestions?
I don't think it is a problem. When I mentioned moisture I meant leaks or when there was a differential between outside and inside temps.
You mentioned that you were going to heat it. How are you going to heat it? Make sure you don't produce water vapor as a byproduct of heating.
Most structures have a certain amount of seasonal moisture that comes into them and goes out of them and they are fine. If you have humidity in the summer come into the structure it will absorb it and then it will leave in the fall. By the time it gets around to winter it will have already gotten lower.
The problem is when people put in vapor barriers in the wrong place or produce moisture somehow with a heater or showers that sets up conditions that over saturate materials. I can tell when I walk into a place that there is something wrong. I can feel the excess moisture, smell mold, or bug spray. I can smell a heater that is not vented. These things set off alarm bells with me. Something is wrong! For some reason the people in the house don't have the wherewithall to know this. You are aware of these things so you won't have these problems.
The dry wall will be fine.
Yes - you should use an exterior paint on the interior walls, not interior paint. The finish may not be a smooth but it will hold up longer.

Prime it with shellac-based primer, i.e. B.I.N. primer/sealer. It makes a good vapor barrier.
Use durabond for the first coat and easy sand for finishing.
Premixed bucket mud will not work.

No? What kind of failure would it experience?
I've never seen compound fail from cold temperatures. Around here it rarely even gets to the single digits.
Will the code let you use T-111 - No tapeing, no painting.
