I have a Toyota Dually work truck. Adding air to the rear tires has always been a royal pain in the butt. No one ever has the type of air fitting that will work on a dually. I was so very pleased when I saw this compressor. It's not one of those little "toys" you use to add air to your bicycle tire. This is a "real" compressor that actually moves air at a reasonable rate. It fills my tires as fast as I had hoped and it's lighter and quieter than I expected. I love it. It's well thought out and the perfect tool for the job. I highly recommend it.
