Something is screwy, yeah the VIN reads as an H series (single rear axle) and the rear axle gross is only 16,000 lbs., which is right for a single drive medium duty. Frame looks a little wonky above the lift axle. Truck probably started life as a de-rated heavy 4X2 duty fleet truck and somewhere along the way was stretched into a tandem. With 'Binder rear axles....
