Query: Woodman

I am looking for a block heater for my Chevrolet pick-up, I was led to this site and this product, Now from what I can see of this thing it does look good, But just what is it? You do not have a good discretion of it anywhere. I don't know if it will work on my truck or if it is for a milk tank. Thank you I'm still looking for a heater for my truck.Don the Woodman
