So how much do I have to derate the ratings if I want to go up a 30% grade vs a 12% grade. Much less the 20% grade of my driveway? 35mph is pretty dang slow up a 4% grade these days, granted in 100F heat with AC on, but still, 5mph lower than my states min on an interstate!
Well anyway, obviously my current feelings on the new rating system, better than the old, but still, useless for contractors or other folks that spend a lot of time on local roads where there is not a max % grade, as interstates have. Been stalled out below gvwr, also went up a grade at the same wt as the stalled out rig, with one rated half its wt, but went up at 150% of its rated gcwr!
When they start giving us multiple ratings per say like mdt and hdt trucks, ie how it will perform doing typical hwy work, 60 mph speed held on a 3% grade, and min 15% gradability, off road/contruction is 1% freeway grade at 55mph and a 30 to 70% grade it can pull......now I have numbers I can use, but current specs, still pretty useless knowing if I can get up a clients 100 yd long 33% grade driveway on Lake Washington. Or the 15-18% grades in downtown seattle, or the 23% grade for one block on Queen Anne Ave on the North side of Queen Anne Hill in Seattle! Probably stall the wanna be twucks out!
