rsb502 Posted June 1, 2015 Share Posted June 1, 2015 bbigrig, be careful with anything shorter than a 230 in a CHU, anything larger than a 56" sleeper and you wont be able to pull a reefer without being really close to the cab, "really close". There are several CH's, not CHU's i have seen around here in the 220-240" wheelbase range with 60" and 70" sleepers and rear mount exhaust that I wouldnt want because Id never be able to move anything I wanted. I know theres a logging company here with a 60" mid rise on about an 06 model that I think was a 224 wheelbase and with a flatbed behind it theres barely 24" from the cab to the trailer. I prefer a nice comfy 4-5' between the truck and trailer, 6-7 is even better,lol. Of course with a 48 or 56" sleeper and side mounted exhaust you get some more space freed up back there. i think Id want a 56' flat top with side mount 7" exhaust and about a 270-280" wheelbase!

Dirtymilkman Posted June 2, 2015 Share Posted June 2, 2015 2015 titan with 55,000 miles on him. I gross 91,000 lbs. Im empty for about 1/8 of the miles I put on. I make 8 stops to fill the truck and I average 5.7 mpg or 6.3 mpg if I keep my idle time under 10%. And I run interstate the majority of the loaded miles at 70mph. But I do burn a gallon of oil to every 2700 miles. Otherwise zero issues with this truck.

Underdog Posted June 4, 2015 Share Posted June 4, 2015 A Gallon of oil every 2700mi.....on a new truck? Holy crap man!I had this issue with an E9. About a gallon every 3,000 miles. Switch to Mobil Delvac and consumption problem went away.Gregg Quote Link to comment https://www.bigmacktrucks.com/topic/39255-fuel-milage/page/2/#findComment-292293 Share on other sites More sharing options...
Dirtymilkman Posted June 4, 2015 Share Posted June 4, 2015 I've always ran rotella and I have a e7 with a million miles and no new bearings and that don't even use oil. But I figured on this one I'd have Mack do the service so they use their oil. I may be switching to rotella on this one........
