Somebody asked about their motorbike...

The Dana 60 steer axle has no problem with that weight even if the truck is diesel. Having the snow plow package front springs would allow something that heavy to be out front with minimal sag.

You can zoom in and see it uses three tubes to support the motorcycle rack, so the carrier is custom.

I question the tie down of the motorcycle and the lack visibility with the motorcycle mounted so high. I'm guessing the motorcycle was just a test of the carrier capacity and the straps were added on as a lark.
