I've seen a few of them go through the local dealer, most were dumps but one had a roll off frame on it. The dealer is using one as a tractor for its parts trailer I see on the road at night. I've only seen one other in use as a dump. I've done some reading on these trucks and the engine is built by International with some Caterpillar refinements and it's available with a Caterpillar automatic transmission! A pretty big undertaking, they will need to sell a number of them to see a return on the development costs.
