bullhusk Posted June 2, 2011 Share Posted June 2, 2011 Also sometimes it will tell you on the Mack door tag, esp. if It's not a Mack engine. My RL700 has V12DD an the ser# of the engine under the truck ser# on the door tag on the driver side. What model R do you have? I just love the R'S!! Ya know what I have not seen in awhile?? a U Model with a Mack V8, years ago Matlack an MTS out of PA used to haul cement with them U's they could scale the axle weight in Jersey an were good in the NYC streets cause they were short BULLHUSK Quote Link to comment Share on other sites More sharing options...
