I like the look of the white two needle front gauge. I chose Firestone over another brand because the compressor can be mounted outside the cab. I didn't realize it didn't fit under the hood. I found what looks like a safe place in the frame spar behind the driver's side transfer case. 01 Superduty CrewCab long bed. I'm giving 4 stars and not just because the compressor doesn't have a built in 5psi auto switch like the other brand. As long as there are no leaks, this shouldn't be a problem. Just keep an eye on the meter and make sure it's 5 pounds.
