Here is a picture of the "U" cab on the R series. U and DM series DM Mixer on subway tracks (note offset cab) The “U” and “DM” series were modifications of the “R” series. A short hood, and the shorter “bumper to back of cab” distance, made them useful in straight trucks and in semi-tractors used in congested cities, but caused the engine to intrude into the passenger compartment. To compensate the cab was offset to the left: the engine “doghouse” intruded into the passenger footwell but left the driver’s position intact. The U was basically a short R, while the DM was an extra heavy duty version of the U often used in 6X4 construction trucks. Like the RMM, the DMM was all wheel drive, but had not only a short hood/offset cab, but also a set back front axle, requiring a model specific fiberglass hood/fender arrangement.[2][3] https://upload.wikimedia.org/wikipedia/commons/thumb/d/d6/Concrete_Benches_on_the_No._7_line_%288510310107%29.jpg/220px-Concrete_Benches_on_the_No._7_line_%288510310107%29.jpgConrad made the "U" cab on their R series dump truck.

Thanks Craig - very interesting. That explains why the Conrad model looks odd.

[quote=Quinella]Dan: Your models are wonderful. I wish they rolled, or do they? Also those pictures of that real yellow R Mack are terrific. I just noticed the Mack bulldog on the back of the side mirror. Old trucks are soooo coooooool. Dan you make the Autocar also as I recall. It's 1/50th? What is your website? CAW[/quote.
Craig belive it or not that yellow mack is actually 1/24! There was a guy on model car mag that did it. Trailer and ex avatar are scratch built. And the mack I think was an amt kit....highly modified.

Quinella,
Mack DM models, both 600 and 800 were also available with long hoods. Very prevalent in the Northeast at one time.

Randy: Did those Mack DM 600s & 800s have a cab that looked like it would fit only one person. I swear I saw a Mack the other day that was moving a house from one lot across the street. I didn't think to take a picture. It had a very long hood, but the cab was so small and was on the drivers side. CAW

Quinella, Mack long hood DM600s and DM800s had normal Mack cabs for the time, just offset toward the drivers side. DM600  DM800

I was looking at that yellow Mack and thinking real. Model? Model. No it's real! No it's a model? Is it real? That is an awesome build. I'm still not sure it isn't the real truck!

The Mack U series and the DM series used the offset cab position. The R, RD, RB, RM, RL and RWL (later Superliner had a centered cab position. All were available in the 600 series. The RWL was available in a 700 series. The DM was available as an 800 series with the long hood and set back axle. The RD was available as an 800 series as well after DM 800 production ceased. The RB is an axle back RD. The RM which was built briefly compared to the other models was the all wheel drive version of the RB and came only with steel butterfly hood as was true of the DM 800 and RD 800. The DM and RD were also offered for a time with a steel hood besides the fiberglass. The U model was built with a light straight tractor frame for use when the overall length of tractor trailers was regulated. The DM 600's used a heavier frame that also had an increased frame height behind the cab for the stresses cause by dumps and mixers. That is the source of the DM designation. All shared a common structural cab. That cab was used for 40 years as it was introduced in 1965 and stayed in production on the RB and DM series until about 2005.
