Rpm range?

[Waterloo]

871, 3.36 gears 18spd, I find the sweet spot right around 1350 - 1400. I haul very light, normally just a few skids in a 53' dry box, and rarely leave Michigan. When I am heavy, I try to keep the rpm's up, she does not like to be lugged, especially with those lousy gears I am cursed with. And yes, I do use the cruise control, and I do have an occasional pull here in Michigan on a few roads I frequent. I will drop out of that and downshift to keep the rpm's up at that 1400 mark. Oh, I don't know how to double clutch, I have forgotten how to do that. ;-)
