You didn't look very hard... there is a lot of info on each manufacturers website... take a look again.

Thank you, gentlemen. I didn't know if it had to do with hp rating or displacement or just some random number.

 

I purchased my Showhauler through Hickory enclosed Trailers. The owner Jeff chooses to drive a pre-emissions truck due to the reliability. There are a lot of error codes evidently with the newer trucks that have to do with DEF or the DPF. I’m in a Showhauler Facebook group and people with new trucks are regularly posting complaints about error codes dealing with the emissions system
