extending slides in cold weather

I have not, and not likely many can say they operate their slides in sub 0 temps. You asked for opinions, so I will say I would not do this, unless maybe an emergency, have to situation. I have electric rack/pinion, that I've used in around 32 degree temp without issue, other than maybe moving a little slower. The rubber wipers can get plenty stiff, compared to 72+ degrees. Severe cold, IMO, would put extra stress on all moving parts, as well as the motor.
