Hi Im David. I just picked up a S83P Hijet Jumbo about a month ago. Judging from the seatbelts, and early number, I think its a 1990. It had a blown head gasket and a bunch of other engine problems when I got it, but I am working through those issues and have them mostly sorted. I will update my progress in the Hijet forum, unless you all prefer the general truck forum for that kind of thing. I plan to make over this truck in to something of a jack of all trades camping, work, hauling stuff, run to home depot or the dump, saturday afternoon drive kind of project. David
