This is from a 1984 episode of "Falcon Crest". The fire truck in the background is visible in this very brief segment only. There's no other camera angle.

I am not sure, but think it might be the same 1981-82 Chevrolet C/K-30 as discussed in these threads:

Can anyone confirm if it's the same make and model?
