Sounds like a normally aspirated Multifuel to me (I presume it isn't a turbo given the small stack diameter), running pretty good. You might want to do the field modification seen on "Saddam's Nightmare" in my icon of applying a 4" elbow to your air intake to get the mushroom off the fender if you get rain or snow (a lot)where you're at. The Multifuel really hates a wet or clogged filter element, and the further it is up off the fender, the better.
Nice Truck....

N.B. Another suggested mod might be to get a new straight stack top made and fit the same with a flapper cover, as it is getting harder to find new mufflers for the NA truck (stock) and rain takes the mufflers out fairly fast if you forget to cap the stack, plus it keeps the soot off you cab, tarpaulin and truck (ask me how I know about that one....).
