JoeH Posted May 21 Share Posted May 21 Im 5'11" and the backs of my knees start to burn when I reach down halfway down my shins, lol. 15 years in R models has shortened the tendons and muscles on the backs of my legs! The +3 can was likely introduced at the same time Mack went from the steel dash to the plastic curved dash. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74171-u-and-dm/page/2/#findComment-552161 Share on other sites More sharing options...

All the old freight companies in the northeast used U models. Big construction out fits were more White/Autocar around here vs the DM back when....... l know that the fresh air door/vent over the clutch pedal of a U or DM. You want to have it closed when its raining. Damn thing collects enough water to flood the cab! .....Hippy 4 Quote Link to comment https://www.bigmacktrucks.com/topic/74171-u-and-dm/page/2/#findComment-552166 Share on other sites More sharing options...
mowerman Posted May 21 Share Posted May 21 Yes, I don’t doubt it would soak your legs. Don’t think I’d ever experienced it. My U model had factory air Quote Link to comment https://www.bigmacktrucks.com/topic/74171-u-and-dm/page/2/#findComment-552168 Share on other sites More sharing options...

What about the DMM ????? lol Bob DMM ==dumper/mixer/massive = no that's not right !! DMM had the raised cabs no front fender wells. set up for dual front steer / front wheel drive/ steel or fiberglass nose. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74171-u-and-dm/page/2/#findComment-552170 Share on other sites More sharing options...
Popular Post Geoff Weeks Posted May 21 Popular Post Share Posted May 21 I could be mistaken, I always understood the 'U" was for Urban, a short nosed tractor to maneuver in tight places like East coast cities. Much like the IHC Fleetstar. 2 cyl under the hood, 2 under the dash and 2 beside the driver! 3 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74171-u-and-dm/page/2/#findComment-552173 Share on other sites More sharing options...
mowerman Posted May 21 Share Posted May 21 Might’ve started up that way, but by 1970 they were all over the turnpikes up and down with freight trucks mostly at night. They certainly made a big splash for quite a while. Thanks for that….

Popular Post RRJordan Posted May 21 Popular Post Share Posted May 21 Just for fun and hopefully without any offense: Many years ago I asked a senior driver what he drove and he said, "An Italian Mack." I never heard of such a thing so he explained, "It has an offset cab--it's wop-sided." 2 4 Quote Link to comment https://www.bigmacktrucks.com/topic/74171-u-and-dm/page/2/#findComment-552195 Share on other sites More sharing options...

tjc transport Posted May 21 Share Posted May 21 Paul, U and DM had same cabs. the difference was in the firewall. U had engine partly in the cab, DM did not. we had a DM with wrecked cab, dash, roof ,and back wall. (a jerk in a 980 was driving through the yard with bucket up and "did not see it" put the cutting edge into the bottom of the windshield area and ripped the cab off the truck) we put put a used U cabin excellent condition on it. cut the DM firewall out, and welded it into the U cab than put it on the truck 1 Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..

I always understood the offset cab was to shorten the BBC. Also for better weight distribution. I'm also thinking early Us were available with a V8 . Like when the R style cabs came out , weren't the Us supposed to be the replacement for the Cs? I remember DM 600s with the engine in the cab like U models ,and that was a small cab (metal dash) Get's a little tough to remmeber as back then it was fairly easy to swap stuff around without much trouble. The DM I'm thinking of had a Coolpower in it with the water going through it too. Way newer than the chassis. DM 800s ? they were just huge. No mistaking one of those bad boys for anything else. I think they weren't limited to inline Mack 6 cylinders either. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74171-u-and-dm/page/2/#findComment-552225 Share on other sites More sharing options...

I looked at a U model back around 1986 Oakland, California Mack dealer it was a dump truck around 1968 had a V8 Mack engine in it that’s when one of those salesman told me they weren’t worth the extra cylinders I’m already seeing here we’re getting different opinions haha I was really surprised that it had a V8 Mack seems like they were no foot room at all… bob Edited May 22 by mowerman Misspelled Quote Link to comment https://www.bigmacktrucks.com/topic/74171-u-and-dm/page/2/#findComment-552261 Share on other sites More sharing options...
