Gulfstream in cold weather
We operate an Elite interior Gulfstream in some very harsh conditions. Average winter temps are -10 to -20 and I have seen -40 on the ground. As long as you drain and purge the water system well, even for a short layover, and take the other winter time precautions that Gulfstream recommends you shouldn't have a problem. Just make sure both you and your cabin attendant allows the interior to warm up before you start trying to operate systems.
