Wouldn’t recommend it. Condensing humidity levels are bad (rust, electrical problems), although I understand Colorado is also dangerously low humidity, which can cause static buildup and fry sensitive electronics.
I don’t know what lubrication the bearings and lead screws are using, but they will have a minimum temp below which it won’t adequately lubricate.
Large temp swings aren’t good either, especially if you’ll be running a print for a long time.
