Had a driver come up to me and ask if I knew why the CNG tractor she just saw had a green hose coming out of some kind of door on the back of it, and it also had some kind of foldable fairing on the back of it. I told her “did you get a picture” which of course she didn’t. Any one know what she’s talking about or have pics? We only run LNG here. She did say it was a KW.
