Yes they’ve been losing customers for at least 8-10 years. It all started around the time of the recession. Municipalities and utility companies really put the kabosh on that kind of spending. The big super turd Ford 6. uh oh had a lot to do with it also.

At one time I believe Navistar was in the works of a new medium duty gas burner line of trucks. Medium duty gassers were pretty much the norm anyway up until the late 80’s for your average bucket truck, small dump, or heck even 1 ton farmer guy. I’ve done the diesel thing and got it all out of my system. After the death of the 5.9 Cummins, there’s not a diesel engine in a new pickup I’d want to have to own.
