ekennedy21 Posted September 12, 2015 Share Posted September 12, 2015 All I am saying is that if it were an rd688sx with a 350 and a 12 speed and 14ft behind the cab sitting on 11.00r24 or 12.00r24 I could see paying that kind of money for it, but that is just me.

ranchhopper Posted September 13, 2015 Share Posted September 13, 2015 By the looks of the interior its sat inside a garage after work every day pretty nice truck. Quote Link to comment Share on other sites More sharing options...
ekennedy21 Posted September 13, 2015 Share Posted September 13, 2015 with 120,000 miles in 30 years, it had a lot of days off from work. The guy told me its a 6 speed 2 stick with 300 plus, 58,000 rears 18,000 front, 12ft behind the cab, on 11.00r22 rubber. It worked pulling that summit demo trailer in NYC so that is why it is short. I am not sure when Mack came out with the rd688sx with a 350 and a 12 speed, but the 300 with a 6 seems to me that it would be under powered out of the city.

Maddog13407 Posted September 14, 2015 Share Posted September 14, 2015 must be a 285 . I don't think they put the 300+ with the 6 speed and if they did it would be an RD612 not an 88. Got the wrong air cleaner for a 300+ to. looks like a 300 econodyne to me. Everyone wants their 285 and 300 to be a 300+.... Quote Link to comment Share on other sites More sharing options...
ekennedy21 Posted September 14, 2015 Share Posted September 14, 2015 I am just going by what the guy told me when I called. What is the difference between a 300+ and a 300? I thought it had to do with rpm Quote Link to comment Share on other sites More sharing options...
j hancock Posted September 14, 2015 Share Posted September 14, 2015 300 is a Maxidyne with a low torque rise engine featuring 5 or 6 speed transmissions. 300+ is a Thermodyne with a more narrow working rpm range utilizing a 10 speed transmission for example.The ad says it is a 686 which is a 300 Maxidyne so the 6 speed matches up. 1 Quote JimIt doesn't cost anything to pay attention.

wfothergill Posted September 15, 2015 Share Posted September 15, 2015 Rd690 would have a low turning(rpm) 300 Econodyne. Quote Link to comment Share on other sites More sharing options...
