I'm not understanding why your asking about Melton trucks with emission issues. Mostly doesn't matter what company, O/O, or what make, model, or engine. These years of trucks have a huge percentage of emission problems. You have at best about a 40% chance of getting on that might not give you to many problems. if you keep up with with it. Personally I don't like them odds. If you don't run cali might look into some off the Schneider gliders for sale. Or check with Fitzgeralds, thy might have some recent trades worth looking into.
Because it does matter what company. I'm sure Melton is like all the rest & jacks with the motor settings which screws the way the emissions work. Also, almost all drivers are not educated on how to drive emission trucks. It's not the same as the old trucks. I'm not going to get into specifics or arguments/debates. This is what I've learned so far in my research. Thanks for your reply.
