Battery powered nail guns cannot shoot rapid fire, it takes a few second in between shots. Also anyone whose played with a nail gun knows after a couple feet the nail spins. The nail gun would only work if you where almost point blank.
Anyone who's ever used a nail gun knows that they don't fire nails at the press of a trigger. There is a spring loaded sliding safety at the nose that needs to be in contact with whatever is being nailed. It is possible for one to hold that spring loaded slide back and THEN pull the trigger, but that requires two hands and is dangerous because it would then fire erratically.
However, when Ash and Lars are looking for Darby, Ash says that he disabled the safety on the nail gun.

Darby spends an awful lot of time out in the wind and snow, but her hair never looks out of place. She also never has any snow on her when she returns to the building.
For a snow storm to have closed the roads, there's little snow build up at the rest area as the night progresses.
