I doubt that. I'll get to that next hill sooner, and have just as many horses pulling me up it as you do. And more gears to play with.
My truck cruises at 65, but tops out at 68 with the hammer down. So about 95% of the time in the areas I usually run, I am below my governor speed. On the downhill grades I'm talking about, ... I-80 in Iowa, the entire state of PA, .. that kind of stuff, I'll let the jake keep the speed somewhat under control & tap the brakes if I need to.
On Sandstone, or that steep grade in VA on I-64 just west of Charlottesville, and on the extremely rare trip I take out west where there are really long grades, I'll drop a gear & run it at whatever the hell speed the jake wants to hold it where I don't have to keep hitting the brakes to keep the RPMs below 1700 or so.
The jake keeps it "somewhat" under control. I do the rest with my foot or with the trans, when I think it's necessary. Geez, do I have to explain everything to you?
Do you drive with your hands on the wheel "two & ten" and the seat backrest 100% vertical and the air seat all the way up too?
