To further answer your question, there are a few things that here in louisville, and at CCE we have come to realize with winter used hydraulic setups, one of our employees drives an s10 with a 2 pump CCE street setup on it EVERY day... including winter
The root of most of your problems during winter months is the temperature of the fluid being pushed through the system, think of it as cold syrup verses warm or hot syrup. Warm syrup is always flowing better... lol. The fluid being cold and thick usually leads to the batteries working harder to spin the pump head like the pump head wants to spin, this coupled with the fact that the batteries are already cold from the weather, will make the battery power drain faster, once your battery power drains and gets down to a certain point it will start killing solenoids(this only happens when batteries are extremely dead). We have not had a problem with cylinder rust, or anything like that, our cylinders are a double O ring, poly pak seal on the piston, with a bronze bushing at the bottom of the shaft.
Basically, the short of it, when its cold, use the system as little as possible, and youll probably have to charge your system a little more. Other than that, a basic hydraulic suspension is far more reliable and dependable than a basic air system in a cold climate.
