with snow, it is more likely that the radio's receiver fried. More often than not, a fried ESC will not turn on.
When you turn the truck on, do you hear the steering servo twitch?
If the problem was just not moving, then Id suspect the ESC, but since you have neither steering or moving, the receiver is most likely. They are easy to get fried, as the openings for the plugs are large and water gets in easy and hits the board.
