Want to upgrade to a Fastrak. Please advise, is this a SUPERDUTY?

I am looking to buy a 2014 48" Fastrak SD that is advertised about an hour away by a private owner. He claims it is a Fastrak "SD". He sent a picture of it and here it is.











Can anyone tell me if this is actually a SuperDuty? I have never seen the SuperDuty stickers on the front advertised with the "SD" abbreviation. I have not seen it in person yet, but the engine picture is the fx691v. Also the engine guard only says Fastrak and does not have "SD" or "SuperDuty" on it.















Can anyone tell me if this is an actually a SUPERDUTY?



Thanks.
