No way for me to know., but I suspect it may have had a plow on it. From the looks of the camber, it may have heavy front struts that cause the front end to be out of whack with the plow removed.
Given it has that cab and all, might it have been used to clear parking lots or HOA's where pavement contact would be a constant issue. That kind of use will destroy tires. Unfortunately, I found this out at low hours.
I see you're in Mississippi, so it would have had to be "imported" for the use I described. I'm not sure why it would have a full cab without climate control in your climate though.
