More than Likely a AC, may be a DK was a Concrete mixer chassis for years then converted to 15' dump body. 250 Cummins, 8LL trans, Hendrickson rubber ride beam suspension. Is rough and will accept a low figure for it. I will be posting photos if I do or do not buy it.
Well I looked, definitely NOT a buy unless you need a cab and sheet metal for one. KK Series, cab was sound, frame is toast where the old concrete had eaten up the rail flanges above the suspension cross member and the owner cut away then welded flange replacements around four feet long on both sides.
Had other issues to where I do not think without MASSIVE amounts of cash could it be road worthy again for any reasonable use.
The bed was used for concrete batch hauls where they did NOT clean it with the 'lining' well over an inch thick 60+% of insides, has a ?second? maybe third floor over-welded on the original(s) underside was really ugly, hydraulics worked well and quiet. Owner tried to sweeten the deal offering enough used tires/rims to make a decent full set and added Super singles for front. The engine is a 290 SC Cummins, sounded good except when hard accelerated where light miss indicative of oil laden push rods, typical for the age RTOF958LL fuller SSHD Rockwell's under. Walking beam torque rods bushings are shot, beams do 'walk' severely on turns and a GREAT amount of steering play just moving it on the yard. Brakes were around 40%, wiring is pretty well a birds nest. Could be usable for a farm ON FARM truck for mucking out barns or such or even a site truck for hauling spoil/debris but not a roadie in any way.
