TeddyBomber Posted February 4, 2023 Share Posted February 4, 2023 Does anyone know what version of this model has the centered cab? I've only seen it once for sale but only remember it being a dm 600 series Quote Link to comment Share on other sites More sharing options...
mechohaulic Posted February 5, 2023 Share Posted February 5, 2023 RD would be the centered cab. R == centered cab, D(M) == would be heavy duty chassis. Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted February 5, 2023 Share Posted February 5, 2023 I was told years ago, that the offset cab of the DM, was for the driver. So he could see behind him really good, due to the amount of 'Backing up' that a dump truck driver and mixer driver have to do.

tjc transport Posted February 5, 2023 Share Posted February 5, 2023 yup. the offset cab gave the driver much better view of the driver side of the truck for off-road or tight conditions.

fjh Posted February 5, 2023 Share Posted February 5, 2023 Joe If you look back on most history of the mack line up most of the large off hyw units had an off set cab The CL350 and a lot of the mining trucks had off set cabs so in my opinion you are correct! also the top forward facing windsheild on the Cl 350 and some mining cabs I think was borrowed from the ship building archives in my opinion! 1 Quote Link to comment Share on other sites More sharing options...
navypoppop Posted February 6, 2023 Share Posted February 6, 2023 It might have helped drivers see out the left side better but how many U and DM's did you see with right front fender damage? It surely didn't help the passenger side. 1 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted February 6, 2023 Share Posted February 6, 2023 So true, Pop Pop... Rookie rods would help.. they helped me.. I even have a homemade set on my extended front bumper on my 1 Ton.. Quote Link to comment Share on other sites More sharing options...
tjc transport Posted February 6, 2023 Share Posted February 6, 2023 rookie rods don't work, they are the first thing steering wheel holders take of on bollards so no one knows they can't drive. 1 Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..

Red Horse Posted February 6, 2023 Share Posted February 6, 2023 I think the U and DM cab came about was because Mack needed a 90" BBC cab. Offset cab allowed them to do that without taking too much driver room away. 1 1 Quote Link to comment Share on other sites More sharing options...

Joey Mack Posted February 7, 2023 Share Posted February 7, 2023 I remember the cable type steps. They were always there, maybe a little crooked, but they were there.. jojo Quote Link to comment Share on other sites More sharing options...
tjc transport Posted February 7, 2023 Share Posted February 7, 2023 we never used cables on the DM800's because the drivers were lazy and would hook to them when stuck and rip them off. we had 1/2 inch link chain welded to the bumper brackets on the frame, and out 18 inches to the bumper. 1 Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..

navypoppop Posted February 8, 2023 Share Posted February 8, 2023 The U models were also designed to allow for pulling those 45' trailers back when the length laws were 55'. I also loved the bumper guide bars on my Macks but with the baby dogs on top. I also have a pair on my Ram 2500 and it still helps to know where the right side of the front of the p/u really is.

Joey Mack Posted February 8, 2023 Share Posted February 8, 2023 Poppop. I have 1 of those little Bulldogs, from a 78 DM I used to drive. The truck came in as a trade- in at the Mack Dealership I worked at... Yeah,. I took it.. he's got the pointed ears.. 👍 Quote Link to comment Share on other sites More sharing options...
ppsyclone Posted February 17, 2023 Share Posted February 17, 2023 Well I have driven Mack mixers with the offset and center mount cab. The offset cabs were for DM and DMM600s. Truck was pretty capable off road. Rode like hell. Liked the off set cab off road, as long as the obstacle wasn't on my right. Road vision was very problematic. Had a wreck one time. I changed lanes to the right and ran over a small car that was not visible in my mirror. Solved that problem with a convex school bus mirror mounted on the right front fender. I have had a strong preference for the center mounted cab since then. Also DMM was very short on leg room and headroom. 2 Quote Link to comment Share on other sites More sharing options...
mowerman Posted February 18, 2023 Share Posted February 18, 2023 Right I am only 5 foot seven and I have the seat all the way back and mine I don’t know how tall guys fit in them not sure about the head room doesn’t seem to be a problem but yes doghouse is right up against right foot Quote Link to comment Share on other sites More sharing options...
