but that trailer looks pretty much useless.
Looks like A/C ducting. No weight there.
I bet a DOT cop will have all sorts of fun with that truck. The VIN says W350 with a 10,900 GVW. That extra axle doesn't mean anything to a DOT cop. He goes by VIN weight rating.
Upfitters can re-placard for higher ratings, right? In my state it is as simple as paying for the tonage to cover the load. Snoking
