[RC] that rpm 'thingy' is called a tachometer - Kearby, Kate G Civ 748 CBSG/IS
Crusing it should read about 2000-2200 RPM , if you are
winding it out to 3000 very much. Should be when you are picking up speed to
get on hiway or just before you shift up. More than that I’d be hunting
a bigger truck and in the meantime keep an eye on things like engine oil temp.
the higher rpm’s, that’s revolutions per minute your engine is
going, the more gas you are using. The faster you are wearing out your oil and
your engine. People that are good at understanding RPMs read by the tachometer
can judge their speed and fuel usage and shift patterns directly off it. Even if
it’s an automatic transmission. You may need a shift kit installed, talk
to a good mechanic and tell them what you do with the truck.
