Joey Mack Posted December 30, 2023 Share Posted December 30, 2023 to me,, an RB is an RD on steroids,, heavier frame, if I remember right, similar to the RW, I have only worked on/ driven a couple of them.. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73706-cat-c15-in-a-mack-rb688s/#findComment-544353 Share on other sites More sharing options...
mechohaulic Posted December 31, 2023 Share Posted December 31, 2023 where does the RB come from?? will admit I'm NOT up to modern day model identification . the RB is a ???? . R model with B model parts ??? another sign of the technical standards of today. days back a model number told a person what the unit was. can understand a ==example purpose ONLY R611T = R model 673T with RR trans single axle.. DM 685 S - Dump Mixer chassis / maxi eng/ light suspension ;; and so on ... !! this RB =ole man at a loss. don't even try to examine the newer model numbers.

tjc transport Posted December 31, 2023 Share Posted December 31, 2023 besides the setback front axle, the other easy id is the headlights. almost looks like they are "frenched in" deep into the hood on radiator side. they were big with cement mixer companies here in Jersey and New York. 1 Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..
