bulldogboy Posted April 20, 2020 Share Posted April 20, 2020 (edited) Thanks for the info, I knew that you would have the right answer. I wasn't sure whether it is an RM or not. There is a discussion on SPAAMFAA's Facebook page about what model it is. Most thought that it is a DM but I knew it wasn't due to the normal cab placement.

Quickfarms Posted April 21, 2020 Share Posted April 21, 2020 To me the dm600 was ugly but I could back the truck into some really tight holes and drop the roll off box especially remember one hospital on the jersey shore, had to drop the empty box on the street and back down an alley with the doctors cars all over the place pick up the full box and take it out and then put the empty box in its place. I remember one day they sent me there with a new r model and it would not fit. I got on the radio and borrowed a dm from another driver and got the job done.

It is interesting that in a tandem truck the RM could be ordered with a non driven front axle. Don't think too many were ordered that way! 1 Quote JimIt doesn't cost anything to pay attention.

RM has similar to DMM chassis rails, front axle setup and transfer case. So actually all the powerplant and the chassis. Only the cab was used off a R-model and I suppose it was fitted on its own RM mounting brackets.

It was available with the familiar fiberglass tilt hood or the optional steel butterfly hood. The RD model was introduced by Mack in 1970. The RD was built with heavy duty components for severe service. That would be a good chassis for the weight of a fire truck tanker. Couldn't that be a R-model with butterfly hood? Mack chassis (frame) brochure indicates RD (taller) frame railf for an R-model firetruck Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/62132-why-do-the-dm-series-have-the-strange-cabs/page/2/#findComment-450804 Share on other sites More sharing options...
