Hello everyone, new poster here but been looking around the site a while. Wanted to get some opinions on a Mack I'm looking at since I've never used one. It's a 2000 CH CH613 with E7 motor at 350 HP. It's got 310,000 miles and just had a new turbo but in. 10 speed manual tranny with 417 rears. Overall truck looks extremely clean, owned by a private guy, new tires, no leaks, just a real well kept truck by the looks of it. Is there anything to worry about with this truck? Do you think this combo has enough HP to pull 80,000 at 65 mph? We run end dumps and it's about an 80 miles round trip but hardly any hills. Also curious about low end torque on these things? We go in and out of fields and have to start from standing still with a full load on soft ground. The truck I'm running now (International 8100 with M11 cummins) struggles mightily to get moving with that on. Also any other tips or things to look for would be appreciated. Have a few friends who are telling me not to do it cause they say Macks' are to brand specific/expensive but we have a dealer about 80 miles away that I hear is pretty good. What say you??? Thanks...............
