Just looking for input on expected mileage when comparing different platforms with a similar size cargo area (ignoring the GVW capacity)
Current truck is a
2003 M2106
3126-225/6spd
Single Drive/254WB
24ft box
9.2 - 9.4 mpg
Option 1
Kenworth T800 Straight truck
ISM 425V/13spd
Tandem Drive/200WB
28ft. Box
Option 2
Kenworth T800 Tractor
ISM 425V/13spd
Tandem Drive200WB
28ft. pup, single axle
Option 3
Kenworth T370 Straight Truck
PX-8 330/10spd OD
Tandem Drive/275WB
28ft Box
Option 4
Kenworth T370 Straight Truck
PX-8 330/10spd OD
Single Drive/275WB
28ft Box
Most days loads would be light, say under 10K
The reason for all this is when discussing equipment choices with management (one person really) there is a reluctance towards any sort of tractor due to a previously unprofitable tractor pulling a 53. (which was rarely if ever filled)
My thinking is a SWB tractor, somewhere around 200 - 225"WB with a 28 pup will be the better option as it will be more maneuverable while being only slightly longer than a ST, mileage will be virtually identical to a tandem ST, cost isn't much greater than a ST while being more flexible with loads, GVW is obviously greater, (can't go after more freight if you can't handle the weight) not to mention durability factors. Also IMO, the when comparing the ISM and PX-8, the ISM wont be working as hard as the Paccar will and therefor mileage will be good.
So what do you all think, when lightly loaded can option 2 be expected to return in the neighbourhood of 9mpg? Ideally I'd like to see some hard test data - would Kenworth have such figures? I see test trucks from the Paccar Technical Centre around here every so often so surely they must be testing the stuff. In fact just this afternoon I saw a W900S straight truck with some sort of test rig on it - looks like some sort of sliding simulated load.
