Just looking at the pics I'd say those miles look to be accurate--it looks like new. Some of us just don't drive these rigs very much--mine is 42 years old and just turned 170k. I suspect this 85 was used for a few years to haul a trailer back and forth to AZ--then gramps retired and didn't really need it anymore etc etc. Speaking of AZ--maybe the reason it wasn't driven much was no A/C??
