kentuckydiesel Posted January 16, 2007 Share Posted January 16, 2007 Okay, I think the DM is made to be a dump truck, so I assume it's the toughest of them. The R is a dump or tractor, correct? Is the RW made to be just a road tractor?Which would be better suited for heavy hauling duty? Were they all avalable with axles as heavy as the next one? HP ratings?Thanks, Phillip Quote Link to comment https://www.bigmacktrucks.com/topic/2028-dm-r-rwwhich-are-tougher/ Share on other sites More sharing options...
bulldog man Posted January 16, 2007 Share Posted January 16, 2007 We have owned the Superdog(RW OR Superliner) the DM & THE R . Personally (just my opinon ) ilkied the DM For a dumptruck short hood easier for tightspots the R & RW For log & lowboy tractors . plus i liked the Superliner for the avabilty for a 350 + horsepower motor w/ say a 12 spd TRANNY To pull a lowboy . We have had all 3 MODELS as DumpTRUCKS W/ double frames BUT IN THIS APplication i always liked a DM w/ a 237 or 300 w/ double stick 6spd 18k fa & 44k r/a @ 4:17 to 6:17 ratio on camelback for the pulling power off in the dirt . & double framed . Like i say this just my opion i like all 3 models of later Bulldog aka Quote You Cant Fix Stupid. But You Can Numb It With A Sledgehammer.

mudslut28 Posted January 17, 2007 Share Posted January 17, 2007 My old DM800 has triple frame from stem to stern. Has the 65k rears and 24 inch rubber as well. Has the 2 valves 300 with the 6 speed so the drivetrain is pretty much idiotproof even hauling an average 45 tons. absolutely the finest heavy haulage truck EVER built by any company! The RD800's were the same frame and rears but were just not quite as tough as the dm800's. I have grossed as much as 160,000 on one of my 800's.The DM800's are the kings with the RD800's a very close second or possibly 1A....lol.I have seen 1 R Model with the 65k rears over the years but it was originally destined for South America..had a 350 with a 12 speed...was a heckuva truck. Usually the biggest you can get on the R's and rw's are 58k rears. 65 rears can be had..lemme rephrase that...could be had on a dm600. I will say the 200 series rears intro'd in 97 or so are very good rears. With the r's and rw's the sky is the limit on motors..I have seen superliners and rd's with everything from v8's to cat motors and everything in between. On the dm's the 350 was usually the biggest that could be had.Not sure if I helped ya but hopefully I did a little.

kentuckydiesel Posted January 17, 2007 Author Share Posted January 17, 2007 So the DMs could be had with the heaviest axles, and the superliners could be had with the biggest engines? So the superliner is mostly made to pull something, while the DM was made to carry it?-Phillip Quote Link to comment https://www.bigmacktrucks.com/topic/2028-dm-r-rwwhich-are-tougher/#findComment-9791 Share on other sites More sharing options...

maxidyne237 Posted January 19, 2007 Share Posted January 19, 2007 v-8 macks could be had in dm 800's. i dont know if all of the v-8 dms had dual exhaust but they had twin pipes on the pass side of the trucks with one being taller than the other (staggered) really neat trucks Quote Link to comment https://www.bigmacktrucks.com/topic/2028-dm-r-rwwhich-are-tougher/#findComment-9849 Share on other sites More sharing options...
kevin mccune Posted January 21, 2007 Share Posted January 21, 2007 DM stands for Dump-Mixer, generally with fishbelly frames-a really nice off road truck when equipped with wide floaters.Had to be careful though if you wasn't used to the offset cab a good way to get a sidewall on the right tire pulling on the narrow scales-Kevin Quote Link to comment https://www.bigmacktrucks.com/topic/2028-dm-r-rwwhich-are-tougher/#findComment-9896 Share on other sites More sharing options...

Supertrucker Posted January 23, 2007 Share Posted January 23, 2007 First truck I learned to drive was a 2 stick RS dump. Learned that before I ever drove a pickup with a manual. Got pretty good at double clutching too, never touched a gear and never bogged the engine.
