Bering is no longer in business. The story went something like this: Berings were designed in the USA, and produced by Hyundai Motor Co. Daimler Chrysler owns a sizeable share of Hyundai, and of course Daimler Chrysler owns Freightliner. Bering's owner alleges D/C forced Hyundai to stop producing the trucks, and then used the Bering designs for Freightliner's line of medium duty cabovers. Bering was planning on building a new plant in VA to produce the trucks themselves, along with a lineup of the first totally new name, newly designed class 8 trucks in the USA since Kenworth. All of this fell apart with the loss of the Hyundai produced trucks and Bering folded.
I think the Bering cabovers had a little Detroit V8 in them, not the Cummins as mentioned. Most of the chassis components are common items. With the company being gone and the trucks no longer supported by anyone, special parts that are unique to the Bering trucks could be hard to come by. May be close out prices, but probably better to spend a little more for something that won't be sitting in the lot if something unique is needed for it. A truck that won't work won't make any money.

Correction- a couple Berings I see on e-bay have the Cummins ISB 5.9 as mentioned, a very common and reliable engine.
