Had the pleasure of pulling a coal bucket with this gem for a whole two days. Single stack Mack with a window in the back. Early 80's R-model. Bulldog.jpg

I have owned a few of those, and worked on a driven a whole lot more of them. I thought they were the best on-off road vocational trucks until I bought my first CH.

I drove a DM600 10 wheel dump for 2 years, probably the most reliable truck I've ever driven. The only time it let me down was when a 50¢ hose clamp blew off one of the boost hoses, I was back on the road within an hour. Cab was cramped and ride was terrible but that truck got the loads where they needed to go!

There are a lot still running in Central America. They love Macks, especially R models. If they can't kill them down there after having countless miles and hours put on them up here, that says a lot about their build quality and durability.

I have a friend of mine in Costa Rica that runs two R model tandem dumps. I would guess they are early to mid 80's models but it was hard to tell exactly with all the "modifications" that had been done over the years.

Thats my understanding as well CM. My customer that still runs the 3 R model macks have sold other R models in the past to a truck broker that ships them to the middle east.He said the like them over there as well.

Was privileged to run team on a 1955 H63 Mack from Columbus, MS-To LA or SF and a few into Seattle for Beneke Corp.
Toilet seat manufacturer-Big market on West Coast.
Believe the tractor was "purebred" as had the Mack engine, duplex transmission (5 & 2). Was a sturdy little horse. We ran
5 on, fuel/feed/change for 1 hour, then 5 off. All you had to do was get in, close the door, open it 5 hours later and do it again.
Lots of miles went under those wheels.
I have some pics of it in the yard at Columbus and when I get time and approval will post them

Those trucks were made before Volvo contaminated them.
"No-SH*T" …willie….. funny tho that Mack used the same cab right thru to the Super-Liners …. very minor changes to make them maybe more comfortable ??? …. LOL ….. That twin stick might be the early version of the 12spd before they had the big round knob on the stick ….. Cheers

We go the Bahamas every October, there all old USA R models all over the place. Most run with big bodies, no mud flaps and no cover. On this trip saw an ex Yonkers contracting DM on the road.

Hey, Only way to drive an "R" model. Gouge on it and go. Let the black smoke roll. Get the guy with the little "tackle box" tool it in Lakeland, FL to add some washers in the pump.
Just saying...

The DM600 was the very best site truck ever made with no exceptions if specced properly.I like the steel cab better than the glass cab but that didn't make any difference about handling on the job site.I liked the 250 with the quadruplex better than the Maxidyne but if it was equipped with the maxidyne I would want the transmission with reverse in the auxilliary,that was the most versatile setup,the only thing that you gave up with that setup was being able to catch it on the rebound if you needed to get out of a bad spot quick because reverse even if you could catch it quick enough was about two gears lower than you would have been going forward and you were dead either way,if backing in got you in trouble when you got it in a forward gear you would be geared too high to move out of the soft spot.
I am going to post a couple of pics of our fleet early in my career as a mixer driver,I worked for this company 21 years in different capacities until I moved on with my life.Ron Gcrop0006.jpgcrop0002.jpgcrop0003.jpgcrop0004.jpgcrop0005.jpg
